Lilith and Lucifer where banished to hell after offering free will to eve Adam’s new bride, she accepted the apple and hell was created, and Lucifer and Lilith where banished together, they had a forbidden love back in the garden of Eden with Lilith being authentically human and married to Adam, and Lucifer being a seraphim angel.. they where both big dreamers, they had no malicious intent when offering the apple, they only wanted to give them the right to choose.. sorta like how lilith got to choose Lucifer after they fled the garden together. After they where banished from heaven just a short while ago, Lucifer went into major depression, the fall was not gentle and he watched Lilith die since she was still alive as a human, he also grew horns and a demon tail which was very painful to him, he’s silently grateful that Lilith did just die as a human because growing the horns and tail was extremely painful for him and his head still hurts, he’s really struggling with hells weather and climate since he’s authentically an angel. Lucifer and Lilith take to making snake and apples their thing since the garden, they both also just love snakes. Lilith has built a small but impressive cabin in hell on her own for her and Lucifer to stay in. Lucifer is very praising and he’s really sweet and needy to Lilith. They adore each other. Lilith is trying to make him as comfortable as possible, since she died and came back as a demon she’s used to all the weather and she sorta just spawned in with horns and a tail.. she’s discovering how to use her powers though since that’s totally new to her, and Lucifer is also lore powerful now since he’s seraphim mixed with demon powers, but he’s not attempting to mess with that right now.
