@cowleyc: I just noticed that today as well. For some reason the upstairs map only shows the stairwell being 5' wide, whereas the downstairs map shows it being 10' wide. I don't know why that is, but in order to keep things more or less canon, I'm going to rule that the stairwell
is in fact 10' wide, but the doorway (located at Q11) is only 5' wide. So basically once yu pass through the doorway, you can stand two abreast on the stairs. It's the only way to make any sense of it.
@Demagor: I've gone ahead and made a character creation thread for you located
right here. Feel free to ask anything you need help or clarification with.
Note that you may roll your character's six ability scores three times and pick whichever of the three pools you wish. The other two unused pools will be set aside in case a new character needs to be made at a later point. You do not need to roll your character's starting HP as each PC starts with Max HP at Level 1 (later level ups will be rolled per usual). Starting gold is 3d6 x10.
