I read over the opening again and this is what I got:

1. Why did someone write the demons to have been imprisoned on a floor other than the one the angels were on? I have no idea. Someone started that and confused everyone.

2. It is a spire, which the GM also calls a castle...so idk anymore than that.

3. If you originally had your character wake up around the bowl crew, then any demigod who woke up after your character should have seen. Because if your character is a Demon, and you had him or her travel to find The Wise Bird and the Dragon, you were right smack dab in the awakening chamber of the Angels. But we had someone writing that they were below this chamber on another floor and they are not. My character hasn't even climbed the stairs yet and so no one should be assuming that he is on the surface. He isn't there yet.

4. The palace is 30 km away so that castle is something else. Some unnamed Etruscan garrison.

So really, everyone should be on the same floor unless you wrote your character reaching the surface because there was only one floor you had to climb to get there.
