Hi! We're planning to reveal the full ranking system in two weeks (if we manage to tweak the last details on time) so look forward to that. In the meantime:

• No, muses will not be sorted into the Nexus.
• You won't be able to get 'resorted', but you'll be able to live in another sector once you reach a certain rank. Or if a friend lets you stay at their place.
• You'll obtain powers based on your sector during rank-ups, but we do have a system in place to obtain other sector's powers which will be revealed later on.

Hope this answers it!
