This gave me an awesome idea
Chrysalis hears tell of the Lord of Lies and she fancies herself the Lady of Lies so she invades Belial's domain disguising herself and her changelings as a new breed of demon and she herself becomes his concubine and eventually, she and her changelings are discovered and they attack from within and the battle comes to a glorious end as atop a ridge Chrysalis and Belial battle one another, but who would win?
