Arbiter of Ash is a Precursor/Primeval, the civilization who first had to deal with Cataclysms. His job is to hit the big CLEAN OVEN button when Corruption starts shitting up the world. I assume he's working for Vridi, the missing 3rd sister of Solaris and Lunaris. He was supposed to initiate the purge during Vaal Cataclysm but was punched in the nuts by the POE2 player at the behest of Doryani.

Then an Abyss Lord shows up and steals his powerball.
