Living Tribunal
The entity: The Living Tribunal is a vastly powerful humanoid entity who has existed as long as the universe itself, and whose function is to safeguard the multiverse from an imbalance of mystical forces. Possessing untold power, the Tribunal will act to prevent 1 of the universes from amassing more concentrated mystical powers than any other, or upsetting the cosmic balance and threatening the other universes. The tribunal will also act to prevent a grave imbalance between the mystical forces allied with good and those allied with evil within 1 universe. Usually the Tribunal leaves matters involving a mystical imbalance affecting only Earth's universe to be monitored by the universe's "abstract" entities Lord Chaos and Master Order, and to be dealt with by their creation, the In-Betweener.
The Tribunal is willing to utter the Incantation of Oblivion, obliterating an entire planet, to safeguard an entire universe or the multiverse itself.
The Living Tribunal manifests itself as a being with 3 faces which represent the 3 sides of the Tribunal's personality. Its front face, through which it usually speaks, stands for equity. The completely hooded face on the right side of the head represents necessity, and the half-hooded face on the left side stands for just-revenge. All 3 sides of the Tribunal's mind must be in agreement when judging a case requiring possible action before the Tribunal can intervene.
The spells: Unrevealed, but most likely will only consider granting an entreaty that deals with the very balance of the cosmos themselves.
