Gridania is like a warmer Ishgard - you have a caste system (one of the closed off areas of Gridania is essentially always blocked to you because you're not part of that caste), blind worship of entities that are essentially too powerful to ignore and impossible to please, in addition to blatant racism towards Duskwights and Keepers, with a side dish of accidental genocide vs. Ala Mhigans.
