After Scanlon Shorthalt brought the abomination of a Naga to it’s tortured end, the Vox Machina vowed to Nostoc Greyspine to put an end to the darkness now bubbling up out of the bowls of the earth. The team quickly gears up and makes their way into the mine, and begins a miles long trek down into the veins of Khaloor. After many hours wandering the dark, they reach a subterranean river within a massive, inky cavern where they are are attacked by a pair of umberhulks. The beasts are dispatched without too much difficulty, but in a fit of rage and short sightedness, Grog charges toward a flickering light further off in the cavern. He stumbles across several Duergar, dark cousins of the dwarves above, as well as a skittering, four legged brain. The wretched thing is killed quickly, but not before lashing out at Grog’s psyche. The goliath’s mind is broken, and he falls to the ground in a heap.
