You thought you were done for.
The last thing you can remember are those final moments on the field of battle, just as that fatal blow struck you. Then, just as you realized you wouldn't be walking away from this one, a great wrenching sensation overwhelmed you, as though your soul was literally being torn from where it should be. There was no pain, but the dizzying flashes of bright light combined with the sensation of motion should be enough to induce nausea in all but the strongest of stomachs.
It ends just as quickly as it begins, leaving you standing in a wide, circular room that seems to have been carved from living wood. Small shoots of green are even growing from the walls, as though trying to invade this strange space. A single window rests on the far wall; outside it you can see only a flat expanse of gray. To either side of the room, there are curving stairs leading upward, the end of them hidden from view.
You are lying on a bed of moss, large enough to support a person twice your size.
