[ValkyrieSkies]

Aquarian nature can be explained as them having the blessing of some sort of semi-divine Leviathan or maybe even Kraken itself; there's no lack of justifications available. Personally I just don't want to see another species that's effected by Iahsus despite having completely different origins to the other Corrupted; I already think Papillions are a bit of a disconnect from the other three given their origins aren't linked to Iahsus or the dark zones.
