Silas is currently in his mid-twenties, having been on his own for most of a decade. He stands just over six feet and a lean, but fairly muscular build. His skin is tanned from a life spent mostly outdoors and his hands slightly calloused and scarred. His clothing is a mis-match of styles, although generally fairly clean. The two most constant things about his appearance is a pair of glasses with a variety of drop down magnifiers and a bushy beard of uneven length.
His two current companion clanks are called "Tiny" and "Gizmo":
- Tiny is, predictably, about ten feet tall and primarily made from a variety of hydraulic pistons and reservoirs, although a few gears poke out from some central system that is well hidden by hoses. Its "face" is a variety of pressure gauges poking from the top of its torso.
- Gizmo is three feet tall and made from a wide assortment of parts. His torso looks very clock-like, with a variety of gears behind glass, although it has no face. The head is a simple box like design with two glass orbs on the front for eyes and a small variety of antenna which move to provide basic expressions. Its left arm appears to be a heavy duty clamp, and its right arms both end in very fine manipulators. It is currently mounted on three wheels at the end of individual arms, powered by chains going into the torso. It appears to be able to balance on two of the wheels while moving the third in order to navigate stairs.
