A member of the Ancient And Accepted Order Of Bridgemasons, Rustbelt is a shy and folksy architect and a skilled designer for the Lost. All he needs are the right materials, no matter how raw, and a few hours of undisturbed work. He can literally sculpt materials with a wave of his many ring-fingered hand into just the form and shape he wants them, hammering them into place like pieces of a perfect jigsaw puzzle.
