The Transcendent Order, throughout the PS material, has always been portrayed as a neutral faction. They're equally well-regarded by most of, if not all of, the other factions. Philosophically, they devote a lot of their focus on staying in tune with the Universe (Multiverse?), composed of it's many different ways of existing (Good/Evil, Law/Chaos, etc).
As such, it's always struck me as odd that they would headquarter themselves on Elysium, aligning themselves, as it were, with Goodness, rather than on the Outlands, where actions don't have to take on the overtones of a deep philosophical commitment to alignment. If staying in tune with the flow of the Universe is their main objective, then cruel/evil acts are just as likely to occur as kind/good acts.
I personally would have them HQed somewhere in the Outlands, most likely towards the calmer, more contemplative side of things (ie. the "Good" side of the Outlands) rather than on the plane of Ultimate Good itself.
I'm wondering if anybody else had given the topic any thought, or if it's just me.
