Ralston

Ralston Cunningham served as one of the lorekeepers of the Knights of Pelor. He commonly used his knowledge of the history of the order to recruit young men and women eager for glory, and frequently found himself taking them under his wing as they trained. He loved nothing more than instilling the mercy of Pelor into each new batch of knights.
Tybolath Wanderfist Ganu-Matho was certainly the largest recruit he'd ever managed, and yet surprisingly cooperative. He was also possibly the most enthralled by Ralston's stories of past knights. So hungry was he for tales that Ralston may have had to invent a few here and there after a few years. There were seeds of truth in them, at least. In return, Ty (because who ever heard of a paladin named Wanderfist?) told him tales of his ancestors, and tales of what he himself intended to do. 
Ralston was 46 years old as of the Siege of Arroyo. As his duty demanded, he sent his mentee to safety, to guard both him and the survivors who would surely need the strength of an almost-knight.
He, along with the five other senior members of the Order who stayed behind to defend the retreat, are assumed deceased.
