Zerci Krell.
She was a young, ambitious Mid-Demon. Despite her lowly birth, she had immense talent, enough to be recognized by the upper echelons of society.
After being given a formal education—a rarity for someone of her background—she was drafted into the military, where she proved her mettle once again.
After reaching the very peak any Mid-Demon could attain in her squad, and then even in her entire nation, her superiors found her potential to be wasted among the dregs she was surrounded with. After some consideration, they made a decision.
The higher-ranked demons opted for the creation of a special squad—appointing Zerci Krell as the leader. Her elite team—composed of members she hand-picked, and were approved by the higher powers—would be assigned specialized tasks outside the usual purview of the regular Mid-Demon military.
