And yesterday we played a one-shot of Hollow Earth Expedition!
It's 1936, and an Austrian geologist named Adele Wagner is convinced, based on her seismological findings, that the Earth is in fact hollow (her scientific nemesis is the Danish geophysicist Inge Lehmann, who has recently published findings that the Earth has a solid inner core - nonsense!). Wagner has been searching the world for evidence of her theory, and found a strange amulet in the Galapagos - a stone set in a metal frame, marked with symbols that correspond to no known language. Wagner has managed to attract the attention of one Henry Bright, an American industrialist with more money than sense. He has put this expedition together.
The expedition is mounted using the Jömungandr, a submarine unlike any ever built. Constructed with the help of the brilliant young mechanic Sprockets McCoy, the Jömungandr is long and flexible, with multiple compartments joined with articulated sections of canvas and tempered metal. It is therefore much more maneuverable than any other submersible, though it will take longer to dive and surface since it needs extra time to adjust to the pressure.
The crew consists of head of security Karl Schmidt, about 50 grunts and crew members, including one Ronnie "The Sledgehammer" Humprhies. Ronnie is a WWI vet, a huge and intimidating presence, a bit of a cocaine addict, and about as sharp as his namesake. He is, however, very, very earnest, and Schmidt has tasked him with a very important job: If the order is given to "blow ballast," he's to turn a key, through a lever, and eject the last compartment of the sub.
The crew includes a few medics, of course, but one of them is not what she seems. Natasha Pushkyn is a Russian witch, raised by a high priestess after her father killed her mother and then himself, and an expert in the field of Necromancy. She's been searching for a powerful mystical artifact that she believes can increase her power, but has recently found legends that indicate it may be within the Earth somehow. She has some medical knowledge, and conned her way onto the voyage.
Also, Wagner met a young man named Finnegan O'Reilly at one of her conferences. Finnegan (born to Irish parents in upstate New York) claims to have had a pet dinosaur at a young age and has been obsessed with strange creatures - what we would now called "cryptids" - ever since. He's been exchanging letters with Wagner for some time, and she believes that his expertise about bizarre animals would be helpful. Plus, it's not like reputable scientists are clamoring to get aboard an experimental submarine and dive into the Diamantina Deep...
Speaking of that...the Jömungandr departs from southern India, travels a few days south to Australia where it resupplies, and then dives. There's a moment where they pass crush depth that Sprockets holds his breath a little ("that creak is OK...there's a different creak we'll hear if we're all about to die"), and then they descend into the Deep.
The controls show two openings in the sea floor, one large enough to turn around, one deeper but narrower. Mr. Bright defers to Wagner and Finnegan for guidance, and they decide to go into the bigger one. No sooner have they entered it than an immense tentacle flops over the front window!
A squid bigger than any ever recorded wraps around the Jömungandr and squeezes gently! The sub can handle a little of that, but not much, and Sprockets reports such. Karl gets on the comms and tells folks to prepare to deploy weapons, but Finnegan shouts not to - the creature is just curious. If they attack it, it will surely attack back!
Bright believes Finnegan and orders Karl to stand down. Everyone holds their breath, and in a moment the squid lets them go. They continue onward, into the deep at the bottom of the Deep.
Rushing water overtakes them and sucks the sub into a tunnel system! The sub slams back and forth against the walls, and Sprockets takes the controls, expertly piloting the Jömungandr through the caves. Karl, however, in the back of the ship, orders Ronnie to blow ballast, and he does...and a moment later an explosion rings out behind them. It doesn't damage the ship, but Sprockets notes that it means there's no way they're getting through that tunnel again.
The ship rushes to the surface, and Sprockets advises everyone to hold on - and then the sub breaks the top of the water! "That was...faster than it should have been," Sprockets notes, and Wagner excitedly realizes this means they're here! She opens the door and reveals...the Hollow Earth!
They inflate a raft and row across a small lake (how did they surface in lake?) to the shore. Finnegan sees animals scatter as they approach, but not what they are. He peers through binoculars at a flock of birds in the distance, and realizes they aren't birds, they're pterosaurs! The tracks on the beach, likewise, reveal a mix of species, some bovine (but much bigger than anything he's seen), some saurid. Giddy with excitement, he exclaims that there are dinosaurs here.
Bright orders Karl to deploy the vehicles (jeeps and motorcycles) and start setting up a base camp. They walk to the top of a rise and look down into a valley, and see that Hollow Earth goes on forever - there are mountains in the distance, swamps with herds of brontosaurs feeding, herds of other beasts (aurochs and triceratops) on the plains, and deep forests.
Finnegan, however, is already in one of said forests, trying to track the animals from the beach. He senses something behind him and rolls just in time, as a spider bigger than he is lands next to him!
The spider is a hunter - he knows that if it bites him, it'll paralyze him, wrap him in a cocoon, and slowly drink his innards. As much as Finnegan loves animals, he doesn't want that. He pulls the pin on a grenade and tosses it under the immense arachnid...
...back at camp, the others hear a boom from the woods. Ronnie and Natasha go to investigate, and find Finnegan sitting against a tree, ears ringing, surrounded by legs. "IT WAS A SPIDER," he says. "So you blew it up?" says Ronnie. "WHY ARE YOU WHISPERING?"
They gather the legs ("we are supposed to get samples") and head back to the in-progress camp. Bright has Sprockets drive a small team - Ronnie, Wagner, Natasha, and Finnegan - down the hill to check out the wildlife and start getting pictures while they set up the camp. Down at the bottom of the hill, Finnegan immediately runs to the herd of triceratops and tries to make friends with one. He notes that the animals don't seem afraid of people...
Natasha starts looking around for some evidence of civilization, something that might lead her to the artifact, and spots a woman behind a tree, peering out. She walks towards her and tries to stay nonthreatening, and the woman emerges, cautiously. Natasha walks to her and offers her a crystal from her pocket, and the woman takes it and tucks it away in a pouch, and then gives Natasha what looks like a seed. Natasha, taking a guess, scoops out a bit of earth and plants it, but the woman takes another one from her pouch and puts it under her tongue. Natasha follows suit (dusting the dirt off first), and discovers that the seed has clearly been roasted, and tastes faintly of licorice.
At this point Wagner notices the woman and walks over amazed that there are people here. She tries to speak with the woman, but of course she understands no English (or German, or French). Inspired, Wagner holds out the amulet, and the woman puts her hand on it...and suddenly they can understand each other! (Natasha, standing nearby, hearing the native woman speak in her language, while Wagner speaks in her native German, so she understands neither of them.)
The woman introduces herself as Pohan, and she talks with Wagner about her people and so forth. She also warns Wagner not to set up camp on the rise - they will be attacked at night. By what? The word she uses doesn't translate, and whatever the attackers are, they aren't human and they'll take people away, kill them, and eat them. Wagner says that she'll go and warn Karl, and leaves the amulet with Natasha so that she can talk with Pohan.
Sprockets drives Wagner back up the hill to camp, but Karl isn't interested in moving the camp. They're almost entirely set up, and he's confident that they can handle any attack. They'll just post extra guards. Bright agrees, and Wagner grudgingly accepts this. But then they hear gunfire!
Meanwhile, at the bottom of the hill, Natasha asks Pohan if there are any plants or herbs that her people use for medicinal (or magical) purposes. Pohan mentions "blue fire," and leads Natasha to a clearing in the woods covered over in a flowering vine with bright blue blossoms. Ronnie follows, still not entirely sure where he is ("I think we surfaced in Russia?"). Pohan says that blue fire - the flowers - can be rendered to a drink that her people use to pep up before hunting, but the pollen in its pure form is too powerful. Natasha collects some, and even the quick whiff she gets is enough to make her jittery. Ronnie doesn't notice this, but picks a flower and gives it a big sniff anyway.
Ronnie is well acquainted with stimulants, but this stuff is amazing. He feels stronger and faster (and dumber, which is hard), and a second later, his walkie-talkie crackles to life. "RONNIE!" yells Karl "WE NEED ZEH HAMMAH!"
See, the gunfire that the others heard was from the sub! Wagner, Karl, Bright, and Sprockets run back to the lake, and see some men firing rifles at the water. Sprockets yells at them to stop before they puncture the Jörmundangr's walls, but then an immense crab claw surfaces, rips open the hull, grabs something out of the sub, and submerges. "Oh, no," whispers Sprockets.
Ronnie arrives a moment later with Finnegan on his back, and Finnegan says that blunt force to crack the crabs' shells might drive them away. Ronnie grabs a hammer and runs into the water, smacking down a crab, and it retreats back into the water. The security men drag the sub onto the beach, but it's been torn up. There's no way it's going to be made seaworthy. "We'll have to find another way home," says Sprockets.
Down at the bottom of the hill, Natasha continues making conversation with Pohan, and learns that she came here to pay respects to her friend - he's buried over there. Natasha asks if she would like to see him again, and Pohan is confused, then horrified. She uses the same word for Natasha that she used to describe the non-humans that kill and eat people, and then she runs. Natasha tries to chase her, but Pohan knows the terrain and is much faster.
Back at the camp, the folks discuss their options. Wagner advises talking to Pohan more and meeting the natives; maybe there have been other outsiders here before, or maybe Pohan could help them find a way out. The four of them get back in the jeep and drive down the hill again, and catch up with Natasha chasing Pohan. The others aren't quite sure to make of Natasha's claims of necromancy, other than advising her to cool it since Pohan's people clearly regard it as taboo. They catch up with Pohan (not hard in a jeep), and see her standing in a defensive stance holding a leather strap attached to a carved length of bone.
Wagner talks her down before she...does whatever she was about to do with that thing. She promises that Natasha is not a cannibal monster, and she's not going to do anything necromantic. She explains their predicament, and Pohan agrees to take them to her tribe. It's a long walk, but in the "beast" (the jeep) it'll be a quick trip.
They ride across the plains and quickly arrive at a gathering of people. They have a few domesticated aurochs, and have set up some hide tents, but they are clearly nomadic. At first the natives brace for a fight, but Pohan talks them down and they receive the characters kindly, give them food, and explain the creatures - humanoid monsters with black fur, sharp claws, and bows that they wield with deadly accuracy. They also tell the explorers that there have been stories of other outsiders, but they come from far way, across the swamps, by the sea. ("There's a sea?")
The characters note that it's getting dark, and they elect to stay here overnight rather than try to get back to the camp. In the morning, the natives start packing up their camp to move on, and Sprockets, Wagner, Natasha, and Ronnie head back to camp (Finnegan stays with some of the native boys to try and ride dinosaurs; apparently it's something young men do for fun).
When they arrive at the camp, though, they find...almost nothing. The camp has been destroyed. They find blood, but no bodies, and Natasha notes that the tracks indicate the bodies both dead and alive were dragged off to the woods. They find Mr. Bright and a few security men, wounded, inside what's left of the sub, and Natasha patches them up. Bright describes the creatures, and his description matches the one that Pohan's people gave - black fur, tails, feline in aspect, wielding bows and ripping out throats with their claws.
The characters salvage what they can, get a couple of jeeps started, and head down the hill. They pick up Finnegan, who's been (mostly unsuccessfully) trying to ride hadrosaurs with the native boys. Finnegan considers staying with the natives so that he can be near his precious dinosaurs, but decides to accompany the others to the sea, since they'll need to go through swamps and they'll need his expertise ("if you hear something buzzing," says Pohan, "take cover. Nothing good buzzes in the swamp"). Wagner gives Pohan her gloves, and Pohan gives her that leather/bone thing. She says if there's trouble, spin it until it makes a loud noise, and then run - it'll attract giant wasps.
The characters mount up and start driving toward the swamps. Will they ever get out of the Hollow Earth? Will the panther-men chase them down? Can Natasha find the mystical artifact - perhaps in the possession of said panther-men, who clearly also practice necromancy? These and other questions remain to be answered in....HOLLOW EARTH EXPEDITION!
(Cliffhangers are very much in-genre.)
