So the trials released each content patch will be in the side Warring Triad story quests. So it's safe to assume 3.2 = Fiend, 3.3 = Goddess/Demon, 3.4 = The one not released in the previous patch. So I was thinking in 3.5 = Unukalhai absorbing all 3 like Kefka and trying to kill the WoL since everything else thrown at them hasn't?
