Born from his mother Elma Silvervein and his father Rain Crumblestone, he ended up taking his mothers Clan name after the disappearance of his father the last of the Crumblestone family. As a young beardling he was found to be a natural born digger like his father and is rarely seen without his pick. But unlike his family, and more following in his Grandfathers, Edal Silvervein’s, footsteps he has developed a eye for design and often times will turn the tunnels he has dug up into great halls, chambers, and staircases. Born after the passing of his grandfather Edal, and the disappearance of his father when he was but a young teenage year old beardling, he has never really had a father figure and spent most of his life fending for himself. Bob Silvervein is currently 69 years of age, and is as far as he knows the only child of Elma Silvervein. Due to his isolation and his natural inclination to think the worst from everyone Bob never really had any friends, doesn’t trust anyone, and so far no trysts. He is very well educated in what he has studied, as he spent almost all of his free time outside digging reading books on artistic design, engineering, and sciences.
