Suffering from EPIC.

You were a siren, Lucifer was a sailor.

Lucifer and his crew sailed by the siren's cove, knowing you and your pack of siren's were there. But fortunately they plugged their ears with beeswax to avoid your song of death.

You disguised yourself as Lilith, and you sang to Lucifer. He decided to play along with reading your lips. After all, sirens know the best path back home.
