Drax continues to run north.
He passes by a passage on his right. Then a set of doors (one across from the other. Another twenty five feet of tunnel and Drax burst into a large cavernous room.
The fire is in this room.
There is a goblin on fire. His skin is melting and his hair crackles. It is hard to tell if he is dead or alive. Drax notices out of the corner of his eye a pile of charred goblin bodies lying in a corner. The goblin on fire is not lying down, he is walking around the room, flames licking every part of his body. At the moment his back is to Drax and he is on the other side of the room. But even as Drax stares, the fiery goblin begins to turn.
