Nihility Styxia, the coastal city of intoxication and dreams, where echoes of old songs still drift among the waves. Helektra, Daughter of the Sea, Chrysos Heir who cleanses the Ocean's Coreflame, dispels the murky undercurrents and orchestrates a banquet of revelry for the heroes beyond the sky. The show must go on. Even if hope is as fragile as bubbles, the waves will keep surging forward.
