Chapter 4

Summary
The adventurers find themselves accidentally travelling to an Abyssal dimension under Ylil's control with no means of returning.

Recap
The adventurers felt themselves be transported from the subterranean pentagram chamber in the dark temple south of Chezalia to somewhere else. The dark ceiling above and the floor below them became a starry sky. The adventurers seemed to be on a floating platform suspended in a starry space. Below the platform, a set of stairs to a massive door set into the void

On the other side of the platform, two undead monsters were consuming a corpse. After a short battle, Carnelian used Turn Undead to scare the undead into running off the platform into the void. Upon investigation, the adventurers find that the corpse was a dwarf wearing ornate plate mail armor (we later learn this was the dwarven fighter of the Nebrask party). Gurney took the armor, and Scourpax used Mage Hand to pull open the door.

The door led to a long, high-vaulted stone hallway with gargoyles with glowing eyes along the walls. The more aggressive of the party members smashed the gargoyles, seemingly to no reaction. At the end of the hallway was a large cathedral-like room with braziers aflame with fires of many colors. At the front of the room was a massive wooden bust of Ylil suspended from the ceiling, below which was a large stone altar caked with inches thick accumulation of dried blood. Lenny and Tolko, the only two to fail a Constitution saving throw, became panicked after looking upon Ylil's bust.

The adventurers were then attacked by a half-dozen gooey monsters that popped out of a tunnel system below the room. Helike volleyed flaming arrows into the holes, filling the tunnels with smoke. After a long battle, the goo monsters were defeated. Helike filled several vials up with the gooey remains of their foes and chunks of the dried blood from the altar.

Behind the altar was the entrance to a maze. The adventurers ventured off into the maze and there were maybe shadow creatures? The geometry of the maze was c̶̳̠̥̦̏͑̅ő̴̱̼̣̒ñ̸̥̮̒̕f̷̺̥̲͕͆̒ŭ̵̮͌̚s̶̡͈̪̓ȋ̷̯̫̣ͅn̶̖͍͚̍̀g̶͎͍̣̫̀̉̑ and thankfully the adventurers were able to get out.

The maze led to a final set of doors which opened onto a grey voidspace above and dusty beige plateau of rock below. On the plateau was what appeared to be a work camp of the goo monsters from before. With nowhere to go but forwards and an ominous buzzing sensation in their heads, the adventurers began walking down the rough-hewn stone steps.
