Shard was a male white fox Captain in Gulo the Savage's horde and was Gulo's second in command. Sly, clever, and manipulative, he claimed that he and his mate Freeta were the real brains behind the horde and that the wolverine was only a dangerous weapon to be used by them. He and his patrol of vermin captured Sister Armel and Brookflow and stole the Sword of Martin that Armel was carrying.
Rakkety Tam MacBurl later took back the royal banner of Squirrelking Araltum and the sword from him while rescuing the two maids. Tam pushed Shard into the fire and injured him greatly, causing Gulo to favor him slightly less. Shard was later killed with a javelin in the neck by Skipper, for which his mate Freeta swore revenge.
