You're starting in a library, facing a row of chairs on your right, and a long, locked bookcase on the left. Turn around, and stop at the very end of the longest table that's right in front of you, to your right. You're going to stop on the rug, between the last two chairs at the end of that table. Literally, it's just the one step. So, whenever you're looking at the table, the long table, it's just- you can just see straight down it. That's your end.
