EDIT: Or maybe Guardian isn't even part of Sigmascape and it's just a boss in Fractal (HM)?
Guardian is the 7th floor. Ultima Weapon is in Fractal HM. Ultima shows 4 players and a passage way leading up to it. Also the design of Ultima's boss room is the same as Fractal. If it was in Sigma, the boss room would resemble the floating continent.
