I want to make a book for one of my AUs but I need help choosing one. Should I pick Soul, Mix, Omega, ???(or Mystery), Realm, Time, Solis, Murder, or DT? Those are the Sanses nicknames. The AU names are UnderSoul, MixTale, OmegaTale, ???Tale, UnderRealm, UnderTime, FaithTale, DeathTale, and DeterminedTale. So, which one should I choose?
