Nightshade

In a city filled with lights, glamour, rich men, and beautiful women, there was bound to be crime. And that crime hurt innocents, sometimes just a few, sometimes a few hundred.
That was where Nightshade came in. Her name was derived from both the poisonous plant, of which she was known for, but also how she came in the night, and slipped away like a shadow. But all heroes had their mortal weaknesses. He was hers, and she was his. Nightshade. A name known amongst many, a deadly secret kept by the city.
