Black Sea

Ly'a was a slave working for the mercenary group Black Sea as a spy and thief. Black Sea kept her twin brother, Ly'on, kept in secret locations as insurance that she would complete the jobs she was given and return. This system kept both twins in check until Ly'a stumbles across an ancient artifact linked to a sealed demon during a heist. The demon grants her the power to break the slave collar suppressing her strong magical abilities - for the price of feeding off her human desires.
