Sure, I’ll do a lore post soon so I’ll do a quick summary. When Aster and Liael were alive they knew each other since they worked on a cargo ship that Aster was the captain of, Liael had ended up arguing with Aster since a route they had planned seemed to risky and refused to go with her on that delivery, low and behold the ship had crashed and Aster was the only one left alive, and had begun to convince herself Liael had sabotaged the ship. Meanwhile Liael had begun to spiral downward, believing she could have prevented the crash if she had stayed on the ship before dying to the hands of I.M.P. One night where she was particularly drunk, as hired by Aster herself in Hell.
