Narillia likes to read, but also likes to play with her specialty — trasmutation and blood magic.
She like experimenting with it, changing the forms of others and herself.
She sometimes collects corpses just for this. She has her tastes she likes, much like anyone else.
Depravity comes in many flavours after all.
She can change her appearance as she like, touching it here and there you get different results.
She also uses it to fly. Very convenient, and very good for scaring others. A good old prank.
Sometimes that can create some more spicier encounters. They are always s pleasant surprise.
Whenever she feels bored and alone, she might consider going to the dungeon to perform summoning rituals.
What does she summon? ... well, you can probably see for yourself.
