Anser

Anser, Sentinel of the Capitoline Hill, protector of all of Rome. An ancient magical guardian who can take the form of an unusually well-coordinated flock of geese or of a handsome, muscular Mediterranean man wearing a white tunic, a cape of goose feathers and a goose hood-and-half-mask covering the top part of his face. Stirred to fury when, at the conclusion of the 1914 Giro d'Italia, Fernando José Salas del Monte inadvertantly awakened the demon Tancredi and brought it into Rome. Although at first Anser was of a mind to execute the hapless Spaniard, Fer persuaded him that this was wholly by accident; Anser agreed to grant him a stay of execution if he stopped the demon. Letting Fer go, Anser proceeded to do heroic battle with Tancredi, considerably delaying but not defeating the demon. Fer ultimately succeeded in his task, but then wisely hurried to leave Rome without checking up on its goosy protector; it is not clear if the city would be safe for him to visit in the future.

On what is a surely unrelated note, Sir Gawain had at one point speculated that an ancient group called the Wardens of the Capitol might have been among the predecessors of the Century Club.
