I'm not going to get too technical about it but I'm thinking the castle KI should make for Wysteria should be Tanglewood Way-ish. It could have the tree filled urban feel to it with a lot of nooks and cranies to look out from at different angles with viewing balconies. and have a tower, cave, or tunnel (or something) thats filled with the vines and the ceiling is covered with wysteria flowers. Whatever is decided it has to have the wysteria covered place! otherwise it wouldn't Wysterian! LoL... besides that's my favorite part. anyway, just thought I'd put that out there. any ideas that would make this better?
