Flambeau the Founder
One of the Founders of the Order of Hermes, and the founder of House Flambeau. Flambeau is perhaps one of the more interesting and colorful of the Founders, a devout Christian yet violent magus. His Fifth Edition biography is described in HoHMC 6-10.
The Fifth Edition version of Flambeau was criticized for presenting a more mellow and peaceful Founder. No longer is Flambeau issuing bellows of "Join or die!" across Mythic Europe, and even his death has been mitigated from a glorious death in battle to (probably) either failed peace-delegation or monastic seclusion. This has created quite a fervor in the Ars community, although many dismiss these concerns.
