Much like his twin sister, Soka, Rainn learned his trade early in life while living as an urchin on the streets of Barbarose City. Wanting to step up and keep his siblings warm and fed, Rainn took to pickpocketing and larceny at an alarmingly fast pace. The difference between him and Soka is that Rainn prefers to not take lives unless it is absolutely needed. After seeing his twin sister become dark and twisted during their teenage years, Rainn decided to ply his trade elsewhere, sending back whatever money he could spare to care for his siblings.
Upon his return to Barbarose City, Rainn had changed and grown. No longer a punk child trying to survive, he had turned into a grown man with master level skills in thievery. Charming and charismatic, he became a man that every woman wanted and every man wanted to be which is how he came to be seen as a de facto leader of the thieving community within the city. Soon, he had developed enough reputation and clout to form his own guild, The Dark Shadows… this did not sit well with his sister. Branding him a traitor to their family, The Crimson Claw declared all-out war on the new guild and skirmishes break out in the city on an almost daily basis.
Rainn is in possession of a Shadow Wisp, making him a Shadowmancer Spell Caster, which allows him to manipulate and travel within dark shadows with ease. This is why no one has ever been able to arrest him and likely never will.
