Laquadia

Laquadia is the High Priestess of the Jadeite Order and one of the main antagonists of the game.

In the past, she had a hidden relationship with Crayden.

You cannot increase her affection towards Devon - all options either causes her to maintain a neutral stance towards him or lowers it. Despite this, in the third bad ending, she becomes Devon's wife. Note that all bad endings are non-canon.
