Mawgrim

After peace was made between the Elves, Humans, Orcs, and Goblin-kind, Mawgrim was one of the few left feeling that the creatures of the horde had lost sight of why they were created. He spawned a new religion, still praying to Gruumsh, but modeling himself as the reincarnation of Gruumsh and a messiah figure for the hordes. This new religion spread through the ranks of Goblin-kind, while the orcs stayed true to their old ways and the pact they had made, some even knowing Mawgrim's true nature. Nonetheless, this new religion spawned a new era of war and terror in the First Great Horde War.
