Well, here's the app.
Name: Athis Caran
Allegiance: Generally Humans, but will help others occasionally. Hired to help people or groups with various things every now and then, such as destroying a building or providing explosive mines for a faction.
Weapons: All sorts of devices affixed to his house. Rudimentary mines, grenades, and two rifles as well as a pistol. Gunpowder based rockets with explosive payloads, fired from a box on his roof. Several large cannons (not portable ones) mounted on his balcony.
Appearance: Short, fragile looking man with grey hair. Wears a (slightly too large) leather coat in less than perfect condition with many pockets filled with mostly useless junk, as well as a small backpack and a monocle with a bunch of additional lenses and such that nobody entirely understands the purpose of. Carries a small pistol in his belt, along with several grenades and mines. In possession of what can only be described as a wheelchair with a partially enclosed seat and four legs instead of wheels, operated by steam power and clockwork and fitted with a pair of rifles below the seat. It has the appearance of being about to tip over constantly, and has occasionally been known to have problems that result in minor parts of it falling off, or (once) exploding.
Backstory: Orphaned at the age of thirteen from a middle-class family who worked in the military, Athis was originally an engineer for the local Duke, and left the position after being deemed physically unfit to continue due to having always been fairly frail of body. Athis was very good at his job and enjoyed it greatly however, and decided to start his own business as a tinker and inventor, using the recently technological advances in weaponry and steam power as a starting point. Fairly well off monetarily, Athis has become rather paranoid over the years, especially of the Orcs, and has spent a great deal of the money accumulated from the services and devices that he sells fortifying his house and constructing various weapons. Most recently, he has attempted to sell some of his inventions to the military, especially gunpowder rockets and explosives, but has been generally rejected thus far due to a general distrust of such new and unreliable weapons (they have not been known to be especially safe, and some have occasionally exploded prematurely for yet unknown reasons). As tensions between the races grow however, his offers have been considered more strongly, and show signs of being possibly accepted in small quantities.
