Vergis Fenn was a mercenary in the employ of Gilmer. At the time Gilmer sacked Trantor, Fenn was Gilmer's fleet commander. He tended to be more cautious than Gilmer, and urged his warlord not to be wasteful with Trantor's riches; Gilmer ignored his advice, saying that Trantor had so many riches they could not be wasted if he spent the rest of his life trying.
