I dig this a lot, couple of things before I can stamp it though-
Loyalties: The Sith Emperor, the Sith Empire
I need you to link to the Sith Empire faction here.
I assume this is more curiosa than things he can whip out in battle for a combat advantage?
Areen is simultaneously rather tall for a Muun, coming in at nearly seven feet tall while still maintaining a deceptively strong, yet incredibly thin, body. He often masquerades as a frail old man, moving slowly and deliberately as if taking great care in not to inadvertently injure himself. Yet to those who truly know his nature, this facade is the farthest thing from the truth.
Areen carried no lightsaber and studied no lightsaber forms, and was an incredibly weak physical combatant.
These two parts seem to contradict each other a bit. If I were you, I'd change the first paragraph to align with the second one. Because while the Codex is a bit weary of rare force powers, I will be satisfied with it if physically the Muun is unimpressive and easily beaten. That would balance the two things out.
I'd also add a stipulation somewhere that the Muun can't endlessly teleport, make note that it is a taxing power.
Let me know when you make the edits and I will take a look again.
