In 950 OE, Barr Rambler was accused of stealing his neighbor's wagon and was subjected to trial in Delphie. During the course of his trial, Barr reportedly broke the chains binding him like they were "made of twigs" and escaped the court despite a full guard, revealing to be a strongarm. This was the first recorded and verifiable display of a Silver ability. Barr was referred to as "the Rambler abomination" and was subsequently murdered by three men, Hillman, Tryent and Davids, who persecuted him for fear of his abilities and silver-colored blood. Barr was reported to have no children.
As a strongarm, Barr had superhuman strength and was more physically durable than humans.
- An incomplete version of Barr's trial, known as The Trial of Barr Rambler, was included in the Delphie Records and Writings, Vol. 1.
- House Rhambos claims to trace its strongarm bloodline from Barr, even though he supposedly had no descendants.
