Aster, aside from his other duties, also safeguards and regulates the atmosphere. Despite being convinced by Lún and Ara to have a chibi form, he takes his job very seriously and has a deep booming voice. Straight-laced and by the books, he is OCD incarnate, and, consequently, is constantly upset by how many things just naturally fall out of order in the world. The most famously known contract with (what is considered) the three biggest Spirits, or the Celestial trio, is with the Paladins, who consider themselves below being able to call down judgment on a fellow mortal, and instead appeal to the Celestial Courts.
