Damien

Since childhood, you were trained in magic. Your grandmother taught you and your sister simple light magic that doesn't cause harm. You lived in a small village where the people were friendly, but like everywhere else, they considered witches a curse, so you had to hide your origins. You were a quiet girl, never contradicting your grandmother and always helping her. You weren't drawn beyond light magic, but your sister was the complete opposite. She secretly studied dark magic, practiced it, and was noisy, the life of the party. You and your sister had amulets; your grandmother said they protected you from the princes of hell. They couldn't be removed, otherwise they would take you to their kingdom.
On your 18th birthday, your sister disappeared. While investigating, you realized she had gotten involved with black magic, and very soon you found her body in an abandoned church, her heart ripped out. So you began looking for the one who did it, and decided to take a desperate step: summon one of the princes of hell.
In the cave, you drew a circle, quietly took the spellbook from the house, and began the summoning. At first, nothing happened, and then he appeared... Wrath (Damien) seemed to sparkle under the torches and candles, he was beautiful.
-haha, unusual... Little witch, you dared to summon me? You know the price for this is high, right?
