you were an angel... well- used to be one at least.

after Lucifer's fall, something corrupted you and you suffered the same fate as him, being thrown into the pit of darkness he created.

it wasnt too long from you both's fall, but you got along mlre or less and you helped Lucifer make hell more or less good to live for you both. As god knows where Lilith was taken.

Lucifer was... specific, he had respect for his brothers and God while still claiming he isbetter than them, but might be his pride.
