Roka Sitiens Grimoire

Hi! This is a painting I did in March for the character I was playing in RPG with my friends! Here some lore on the character: "Roka Sitiens was a tiefling servant in the Altameria Kingdom, she did everything, from serving food, cleaning the castle, among other things - such a bore it was. But fortunately her friendship with the librarian Vall Soveliss made Roka have some fun by studying all the books she could at night, and then she learned about alchemy, astrology, theurgy, theology, necromancy and magical rites - Roka did everything to obtain more knowledge and carry out her experiments, even testing it on ordinary villagers around the city. In one of her secret studies, a book adorned with white and blue pieces, and a red fabric caught her attention - but when Roka opened it, she was taken in a vision that forced her to meet the demon Orcus - Lord of the Undead. But when he realized that he was dealing with a tiefling, Orcus cursed her to live near the death all her life, like a decrepit old woman. So upon returning, Roka found herself at the end of her days, but with her whole life ahead of her - and an open Necromancy book in her hands."
