Potentially interested! I really like the worldbuilding you've done thus far, and have a few questions related to it!

Just to confirm, this is an alternate world---when you say the DUA is "resemblant" of the USA, you just mean that they're similar, and this is NOT a fictional future-Earth at all but a separate, distinct Earth-like planet?

The "enigmatic Arcanii" made me think of the word "arcane," so will this RP feature any sort of magic or non-scientific, supernatural force? Or will it stick more to the realm of science-based, technological "powers" and firearm based weaponry?

What are the nature of the mentioned mutations? Bestial mutants are mentioned, so I'm sure those are environmental fauna/flora threats, "monsters" in JRPG terms, but do mutations also affect playable races/people? If so, how does it change their appearance, combat abilities, etc?
