Imps don't often have red hair- which Astrella was born with. Redhead imps are supposed leaders, but Astrella didn't want to be a leader; she wore jester clothing to try and escape this fate, but the other imps still respected her like a ruler.
Travia, Astrella's mother, tried to overrule Astrella- she succeeds in doing so due to her unending pridefulness as well as seniority over Astrella.
Astrella met a wildfolk cat witch named Samael- Samael died of execution and went to Hell. Astrella found his lost soul and brought him back- being an imp, she adored his red hair, and soon, his personality. Samael was similar to Astrella- just funny creatures who wanted to get by without being noticed too much. Astrella and Samael hang out quite often, usually being seen with eachother, both of them being very funny and eccentric as a couple.
