And so it was that the party finally finished off the Chaos Cave. Steadily escalating earthquakes rattled the group as they forced their way into the center of the dungeon, in search of the Holy Relic of Moradin, the Dwarven God of Dwarves and Beer. There, in the center of the dungeon, they found Gorgosh, a Dark Cleric, summoning swarms of the Undead, and his Death Knight servant. There was a force bubble surrounding the entrance, which all of the party save Glacia and her manservant were able to bypass with no trouble. Wading into the ocean of the Undead, Banebeard, the Dwarven Cleric, was an Undead Turning Machine, destroying scores of Skeletons and Zombies each round, and it essentially because a race between the two clerics - Gorgosh raised them, Banebeard put them down. Then the Death Knight entered the fray, pointing it's deadly finger at poor Serendipity the Thief/Mage, recently returned from retirement at the insistance of her paramour Aloud. A deadly Power Word: Kill (aka Fus Ro DIE) spell was spoken, and just like that, no Saving Throw, Serendipity was dead. The pitched battle continued, with Gorgosh slowly retreating to a small back room, where an eerie blue light glowed ominously.
Finally Glacia passed her saving throw and was able to penetrate the bubble, and in two leaps bounded all the way across the battle, and into the back room. So focused was she, that she didn't even see the Illithid playing with a machine in the back of the room. The machine that was casting the eerie light. The machine that extended below the surface into the earth. Which was shaking violently by this point.
Slowly the party whittled down the vast numbers of undead, and closed in on Gorgosh and the Illithid, who turned and fought. The Illithid unleashed it's devastating mind blast on Glacia, but unfortunately, she was in a state of frenzy and apparently immune to such effects. It tried to charm her, with similar results. It was still confused by the lack of effectiveness when Vincent, the militant wizard cleaved it's head from it's body.
Passing through the astral plane on their way back to their flying ship, they saw the Githyanki Astral Fortress Weissehaupt burning as it fell through space. Clearly there was some serious s**t going down. Arriving back on their boat, they saw the earth rippling like water. The horizon to the east, the direction of the Human Lands, was glowing steadily as lava overtook it. To the south, they watched the entire Elven Nation rip itself from the earth and spin away into the sky.
Veravum helpfully pointed out that the Holy Relic of Moradin was mined by the Moradin himself from the earth beneath Sigil, and posessed, among other things, the ability to function like a portable Spelljamming Helm. A debate immediately began with regards to who, if anyone, should be saved from the impending global apocalypse. Some suggestions included an order of Militant Wizards, a tribe of yeti, and "F*ck 'em all, I never liked anyone on this dirtball anyways."
Only time will tell what becomes of the party!
