Many years ago, Lini experimented a lot with body modification magic. She learned and used many spells to tailor her body to her liking. One day, she came across a spell to make herself extra aroused for weeks. However, the spell actually opened a portal to a dimension inhabited by demons. The demons poured in and had their fun with Lini for the duration of the portal. Although priestesses still use body modification magic, some spells are considered forbidden.
