Footpad Calor was a Darkblade who would occasionally assist the then un-named Ätlän-tã Fælcons during their travels. He initially served as Tum Thumble's contact within the Darkblades but eventually became a liaison for the whole party. Worked with Tum on the quest to steal Blood Drinker.
When the party returned to Mastwick after the Demon Apocalypse they met Calor once again, but he had risen in rank to Robber Calor since the last time the group had seen him. It is then revealed that his first name is actually Footpad. So, technically he was Footpad Footpad Calor then became Robber Footpad Calor. Shortly after, he brought the group before Pyre and was bitten in half.
He also served as recruit trainer for young Darkblades. See Darkblade Academy for more details.
