"No idea," Jacob admits as he follows suit, moving fast out of the way of a puddle of the ooze creeping up on them. "Do you want to stop and ask them?"

He is joking of course, but the amusement leaves his face as the stonework under their feet begins to shake and tremble again, a deep fissure beginning to split the floor in two right beneath them.

Jacob's running almost too fast to stop, and he glances back at the shadows following them, and then back to the abyss headed towards them, bricks and rubble falling away into the blackness. It's wider than a man is tall already, and still growing.

"Can you jump that?" He calls out - he knows he can't, but he has another option. And he needs to know now if he needs to grab the other man too.
