Cretaceous period (between 146 and 65 million years ago)
Birth of Mankind
- First human tribes form in northern Africa and the eastern Mediterranean. Nature spirits reach godhood status, starting to require human believers and worshipers. These gods eventually form pantheons that align themselves with human tribes.
First War of Gods
- One pantheon, lead by Lughebu, discovers how to feed on pain and negative feelings of men instead of worship. The benevolent gods fight against those of them who feed on negative feelings of men. The war ends when the malevolent gods are defeated and banished to the Spiritual Plane, and are now known as the Banished Pantheon.
Second War of Gods
- The goddess Tielekku learns the secrets of Magic and teaches them to other gods. Among her pupils are the gods Ermeeth and Hequat. The god Ermeeth reveals the secrets of magic to his worshipers. As a result, they stop worshiping the gods. Tielekku's faction, led by Hequat, defeat Ermeeth and his followers, effectively forcing them to flee. They cross the Atlantic Ocean and form the city of Oranbega.
Oranbegan Civil War
- With the clandestine support of Hequat, an Oranbegan named Mu'Rhakmet gathers a number of followers and begins to demand a return of the people to the worshiping of the gods and the old ways. A civil war soon follows. Mu'Rhakmeth and his followers are defeated and forced to flee to the sea.
Founding of Mu - Approximately 14,000 Years Ago
- After their defeat, the goddess Hequat raises an island from the sea and grants it to Mu'Rhakmeth and his followers to build a powerful nation on it. The previous inhabitants of the island, the Coralax, are forced to leave. One Coralax priest, Calystix the Shaper, summons The Leviathan to destroy the invaders, but Hequat defeats the beast and imprisons it under the island. The nation of Mu is born. Muvians practice eugenic breeding, generation after generation, creating people of incredible magical potential. The goddess Merulina falls silent, leaving the Coralax unguided and confused.
The Mu - Oranbega War
- Following Hequat's orders, Mu finally attacks, and the civilizations of Mu and Oranbega war against each other. The Oranbegans sink their city below the earth to protect themselves. Only a handful of Muvians survive the conflict and are forced to flee. Oranbegans are reduced to spiritual existence and their city of Oranbega is physically abandoned.
