Here was a dilemma. They thought he was an Elf, and Elves don't sleep. If they heard him snoring away, it wouldn't be easy to explain without them learning the truth. He thought about it for alittle while, then realised he didn't have a bedroll or anything like that. The chances of him getting much sleep were lim to none, so it didn't really matter.
He found himself a corner, up against a wall, and sat reading from his spell book. At some point he did manage to get some sleep, and thankfull didn't snore, so it looked like he was just in an Elven Trance. It turned out he'd actually gotten a pretty good nights sleep. He must have been quite tired.
The next morning he spent an hour preparing his spells, whilst he waited for the others to be ready to leave the temple.
