Clou'dea and Mora's forgetting

9,000 years before the First clan war, the three clans gathered together. After a long meeting, they decided to hold a three-way truce and overthrow Clou'dea. With their combined power, they were able to send her away (likely to the Void) and forget about her. Malacus clan and Murex clan then turned on Mora clan, doing something similar and banishing their people and god to the ends of the earth. They have been fighting ever since.

Both parties were interfering with the ongoing conflict between Malacus and Murex clan, providing reasoning behind their forgetting.
