Arkus is a half-orc who was born to the mysterious, dark-skinned orcs of the Underdark. However, he often found their brutish ways troublesome, especially as he found a knack for ingenuity at a young age. He would often escape to the surface world to get away and think; a place that his full-orc bretheren dared not follow him to.
One day, on such an outing to the surface, he was confronted by some intimidating figures in shady robes. Before he knew it, he'd been bagged up and dragged away to who-knows-where. There, they performed demonic rituals, using Arkus as some sort of component or sacrifice. Their attempt backfired, however, when the dark energy of the rituals was absorbed into him instead. The tainted fury unleashed inside of him burst forth, slamming the cultists into unconsciousness with supernatural force. Lost, panicked, and angered, he fled to the nearest exit he could find and ran until he could run no more.
After having some time to himself to sort out his situation and calm down, Arkus realized that he didn't know how to return to his home. His only choice was to survive and find solace somewhere on the surface. Since then, he has become an immigrant in Kenabres, working as a tinkerer of sorts making an honest living. He has also refined his newfound telekinetic powers since then, gaining tight control over them.
