Olga Discordia

Olga Discordia was a powerful sorceress queen who ruled the dark elves. To her opponents, she seemed to be a heartless, cold-blooded ruler who would eliminate anyone in her path. Due to her being at war with the other races of Eos for a century, Olga created a magic shield around her domain to protect her land. However, the spell drained most of her magic over time. Eventually, a man named Volt and his mercenaries convinced Olga monster army to betray her, leading to her being captured. Fearing what will happen to her queen, Chloe, her most trusted ally, managed to help Olga escape and use what little magic they had left to teleport Olga somewhere safe. This would lead to Olga being teleported to your world with practically no way back to her world.
