He was always a big lad - or so his not-momma told him in faint, distant memories, before she was gone, and he took the long walk to the below.
Brother Rat is a large, lumpen fellow, his back bowed from a life spent in tunnels barely tall enough to contain his mass. Among the Kin, his immense strength is invaluable, he hauls debris, wrenches open rusted grates, and hooks crates of sodden flotsam from the choked depths of the sewer drains.
Like all Foundlings, Brother Rat shares a special affinity with the vermin of the underworld. Swarms of sharp-eyed, quick-footed rats cling to him, their skittering presence compensating for his slow, lumbering nature. Though simple in thought, his loyalty and strength make him indispensable to the Kin.
