Through various ways and means all the heroes assembled before the cave entrance, after Dozier, Adran, and Spillz fought two dragonclaws.
The cave entrance:
There are several nude corpses in this room. These are cultists who have taken the worm, unsuccessfully. Sometimes (quite frequently in fact) the kobolds burst from the gut and chest of the bearer, after eating their way out. All the players can tell is that the corpses in this room look like they have exploded from the inside out. The dragonclaw guards hide as normal.
Jon rolled a 20 for knowledge and understood the meaning of this massacre:
Dragons lay clutches of eggs. Any single egg swarms with a dozen or so little worms, who all vie for dominance. They devour each other until the strongest is left, which hatches as a dragon. The same thing repeats itself in the clutch—the strongest dragon kills, eats, survives, and grows.
However, a dragon’s egg can be broken and opened while the worms still squirm within. A human can swallow a worm, which then infests the lower intestine. The worm, feeding off of the human, deposits jellylike sacs of eggs into the stomach, which thrive in the acid. The human periodically (and very unpleasantly) hacks up a mass of grape-sized, soft eggs, which hatch, are fed on the blood of small animals, and quickly grow into adult kobolds.
You’re not a true cultist until you’ve taken the Worm.
The characters then descended towards the next room.
Room 3: Fungus Garden
The characters encountered a room filled with glowing violet fluorescent fungi, everyone made their checks except Dozier who ended up laughing hysterically for a brief period. Other than that, the room was uneventful.
Room 4: Central room
Empty. A big, creepy, empty room that echoes and casts shadows everywhere.
There were spears leaning against the east exit by the stairs.
Room 5: Troglodyte Incursion
The heroes entered the room to find that sweet frumunda cheese smell that Adran, Jon, and Brian encountered years before. There they found troglodytes busy inscribing religious pictograms on the wall, plenty eager and polite to acquire new worshipers, centered around sexual acts and giving birth. Adran was really put off by these guys, but really they were just looking to hang out and have a beer like excellent dudebros. All around good guys, just waiting for their dark god to destroy the world.
The party attacked them and they kept saying that the heroes were is a bunch of real jerks and aggressive pricks. They just couldn’t wrap their heads around why the party was so hostile towards them.
Then they quickly disappeared into the walls.
Room 6: Meat Locker
The trap in this room was foreshadowed with the spears outside in the main room. Basically there was a meat hook trap in roast beef curtains. Heroes rolled successfully to avoid.
Room 7: Drake Nursery
Buncha dudes in this room that the heroes had to fight, along with immature guard drakes. Since Jon rolled a 20 on knowledge from before, he also understood the ritual as to how guard drakes are made:
Instead of consuming a worm from a dragon egg, the victim—a cultist or captive who has committed some offense or crime—is forced to drink the blood of a dragon of the color of the guard drake they are to become. Blue in this case. This cup-full of dragon blood is enchanted so that the victim falls catatonic, but completely aware of their surroundings. Paralyzed with eyes open, a dragon egg worm is released on the face of the victim where it promptly seeks out a burrows into an available eye. It makes its way to the brain, at which point, it begins transforming the person in to a guard drake. As noted in the description, the drakes can understand draconic and any language they knew in life—because the mind of the person transformed is whole within the beast. Trapped inside an alien body they no longer control, they suffer as prisoners for the entire life of the creature, which, since barring accident or murder, guard drakes appear to be immortal, can be a long time.
So that was neat.
Room 8: Barracks
This room looked like a frat house, but instead of having beers, they had people. Half-eaten rotten corpses lied everywhere, flies were swarming around, vomit and crap strewn about in piles.
Room 9: Dragon Shrine
Description: This chamber has been enlarged and reshaped from its original form. The floor and three of the walls are smooth, and stalactites and stalagmites have been polished into gleaming columns. Every surface glistens with moisture and the air is warm and humid. The flat walls of the chamber are decorated with shallow abstract carvings of dragons. Dragons’ tails coil into intricate patterns and knots that flow across the walls. The creature portrayed in the northwest corner stands out: a five-headed dragon, rising from an erupting volcano. Other dragons, which seem dwarfed by the five headed monstrosity, flock to its side. A small, wooden chest with silver and mother-of-pearl inlays sits on the floor in the corner, in front of the monstrous dragon carving.
This is where Carl’s character met Dangdedrosa, and killed him too.
Also, there was writing on the wall:
The sorrow black journey across the steppes over pale horizons unto judgement day, the path into the darkness of eternity, the new kingdom under the wings of the Dragon, ruler of the hidden truth—for all time.
The chest was trapped and had loot.
Room 10: Dragon Hatchery
The walls oozed acid and every minute the characters were there they had to roll a con save.
Black guard drakes
A Roper that Adran really wanted to fight, even though the DM gave every possible reason not to. The group eventually convinced the Roper to head to the meat locker for more food.
The found dragon eggs and destroyed them. Carl’s character would later find this out and was super pissed, though it wasn’t that much of a surprise because his character is basically a giant batman.
Room 11 and beyond: Frulam Mondath
They killed her and learned that Rezmir has assembled a caravan and is on his way to Baldur’s Gate, and then Waterdeep.
