Magnus Beauregard is a tinkerer in Blood Gulch. He is responsible for quite a few buildings, gadgets and weapons in the canyon during the 3rd Generation. Magnus is an awkward yet friendly nerd who is willing to fix any problems he can, only occasionally asking for some form of compensation.

Magnus built and owns his Workshop, which is attached in part to the Cafe. He also built a subterranean village for Neutrals to stay, naming it Stonehold (occasionally referred to as the Magnus Bunker).
