Early life
Prior to encountering Jack Sparrow, Stryke had dabbled in dark magic, paying for it with a changed appereance-that of a green humanoid goblin-like creature. A sliver of ruby, which he wore as a talisman, gave the appereance he was normal, but to make it permanate he needed to find the rest of the ruby.
