Not quite the same

Draco blacks out after a rather harsh punishment from his father. Uppon waking, he realizes that he was not anywhere he knew. Confused, hurt, and in pain he wanders about the forest where he woke, only to be taken to some sort of council, and inevitably getting himself in quite a bit of trouble after realizing...He was in another world. Not only that, there was a Dark Lord afoot, and despite how much Draco may dislike it, he was not about to force another world to give way to a dark lord. Especially since he was stuck there for the foreseeable future.
But it is not easy keeping his identity hidden, especially with an ever observent, and curious, elf.
