What is Proxima?

'''Proxima is a form that lasts 48 Earth hours, the Avatar unlocks their true potential and gains Deity King-like abilities. The first one ever to get Proxima was Crimson, he had gained the form and was able to stop time indefinably, use unlimited energy, make realm portals wherever, summon anything anywhere, and when he had killed Simul, he used up his form to collide the 10 Realms to create Realm 0.'''

Realm 0 took everything good about each Realm and stuck them together to create an Ecotopia filled with animals of all Realms.
