The Tribunal was created shortly after the War of Humanity ended. The Elder Gods Miramar, Daedalus, Proteus, and Phaestus made up the Tribunal, as well as the Aldar Han-Tolneth. Its purpose was to determine an appropriate punishment for the Triumvirate traitors and Pazuzu, the demon prince who nearly won the War of Humanity for the Triumvirate forces.
Proteus, having loved Lorielan before she joined the Triumvirate, advised that she be banished to the Crystal Realm, where she would rule over the Kx'Khrah as their Jade Empress.
Miramar sentenced Khalas and Agatheis to an eternal life of loyalty to Proteus. Khalas was imprisoned within a statue that now sits in the village of Tomacula, and Agatheis was transformed into a unicorn, stripped of his almighty intelligence and elemental power.
Han-Tolneth and Daedalus then sentenced Han-Silnar to a life of servitude to Lorielan in the Crystal Realm.
The Tribunal also decided that Pazuzu would be banished to a newly created Chaos Plane, accompanied by Prince Slith and his undead followers.
