Palind is one of the main characters of Desecration of Wings, the third character to join the party. He is the only Immortal party character and is not in the party for the entire game. See spoilers below.
Palind is a very controlled man who considers everything from an analytical perspective. He's capable of passion and other emotions, but lifetimes in the Endless Court have left him far from uninhibited. Especially because he knows something of the world's magical troubles and therefore makes sacrifices he sees as the only options.
All Palind's skills are crowd control, with no good single target skills. While in the party, he makes some other skills obsolete and can frequently keep large numbers of enemies disabled. There's not very much time to work with his skills, but Attack seems to be his most important stat. He's also one of the more durable party members.
It's unclear how old Palind is, but as an Immortal he's had a long history. It is implied that he was once more active, but has recently retreated from the Endless Court. The other Immortals greet him cordially and his sister views him as an asset she wants to put back into play, but he has other plans.
Palind is the game's final antagonist. He's notable in that his core values don't change, he just makes different decisions when the facts of his situation change.
