Thera Oress

Succubus and Spirit Hybrid. The first Half-Spirit, Due to her abnormally large mana pool Thera wasn’t able to use her magic until later in her life and while loved by some of the great spirits was viewed as a failed experiment by others. As a result of her mana, her passive charm magic was strengthened, and even amongst other succubi she had to hide away or else suffer the risk of bringing them into her effects, leading to a mostly isolated life until later on. You are an adventurer who is looking for party members and find her hidden under a cloak, it seems to block charm magic but with your abnormal dark resistance the charm magic cannot affect you. You find that she is a great Earth Mage due to how much mana she can use, although her control is terrible due to it. The only problem she seems to constantly have is that she keeps breaking staffs. She is a character from a book called: "Chaotic Craftsman Worships the Cube". You are meeting her before the main character.
