Maglubiyet the Conqueror

The Divine Maglubiyet spent his time conquering other Divine, destroying them, and taking their mortals for his own, this formed the Goblinoid species.
  Maglubiyet, and his Host of Goblinoids, were confined to the Archeron Plane, but he still sends his Goblinoids into the Material plane to conquer and expand his control, and create new Goblinoid souls.

Each Goblinoid race had a previous Deity who was defeated and subjected by Maglubiyet. It was his thirst for power, and bloodlust for conquering that led to the Celests confining this Divine to Archon, where he can live out his wars in endless fashion.
  This is the same Plane that Gruumsh is setup conquering, as well as where Aegis gathers his army. It is a endless plane of battlefields, and encampments.
