The venerable Mandalorian rally master armor was a relic of the Old Republic-era, a set of Mandalorian armor used by rally masters, the battlefield commanders of the Mandalorian wars of expansion. Almost all of a suit of this armor was located at the Museum of Mythos on the planet Kalevala until it was stolen by Crimson Dawn, the crime syndicate helmed by Dryden Vos. The armor then became part of Vos's collection on his personal yacht, the First Light.
