Kuma races after the goblin to the north, disappearing from the rest of the party's view almost instantly, as they take a few moments to once more climb over the barricade before chasing after Kuma. Jerek, seeing how the others are slowed by the barricade, and that Kuma is already out of sight chasing the north-running goblin, decides to jump it instead--and succeeds! He moves into position so that he can see the goblin running through the western room, if dimly; once again, Heirmund's light is being taxed to its limits. He lines up his shot, releases his arrow--and misses, the arrow bouncing off the stone between the goblin's legs just as it reaches the far door of the room. The goblin shoulders the already-loose door wide open and flees into a dimly-lit, smokey room, quickly angling out of Jerek's narrow line of sight between two doorways.
((Jerek's jump check: 16+0=16. Attack: 7+3=10.))
Kuma finds himself in even darker circumstances. However, he's also only in the corridor Lehko glimpsed yesterday and described to the rest of you, and Kuma can still see his enemy, if just barely. He reaches the fleeing goblin just as the goblin reaches the closed door at the far end of the hall. There's no way the goblin can get the door open in time. Or at least, there wouldn't have been--if the ground hadn't opened up beneath Kuma's feet. Jair and Ydyr are both just entering the hallway and vaguely see Kuma's dim, large shape simply vanish.
In an instant, Kuma goes from swinging his sword triumphantly at the goblin, to falling into utter blackness. He doesn't fall far before striking the ground, but he is now utterly blind, the only light he can see being a very pale twilight that is far too far away to illuminate anything in this pit.
((Kuma's reflex save: 5+2=7. Falling damage: 2.))
