The party gets separated, some going forward, others backward, while some stay inside the darkness.
Borric moves forward and out of the sphere, along the right side of the stairs, where he sees Varrath standing another 20 feet away and near the far wall. Francis moved backward and bumped into the wall shortly after leaving the darkness, but was able to see Varrath from his vantage. Varrath laughed once more and flung something from the folds of his robes. The object seemed like something out of nightmares: a black blade of some sort with the lively twitching legs of a spider. The spider blade missed Borric's left cheek by just a hair and disappeared into nothing.
In the next instance, Varrath touched the wall behind him with his hands and crawled upwards like an inverted spider until he was about 20 feet off the ground and staring down at the party.
Sir Richard stumbled backward to end up next to Francis, while Duncan popped forward and stood next to Borric. Krindorf finished his spell and was still in the sphere of darkness but could gather the basics of what was going on because of the hollers and yells.
