If you have a random event idea post it here
Here are mine
Didact’s Return: “Time was your ally, human, but now it has abandoned you. The Forerunners... have returned." Mantle’s Approach begins to rampage around the galaxy (if possible starting with human worlds).
New Colonial Alliance: Militia forces slipspace in and lay siege to a UNSC world (economic downturn as well)
Blooding Years: Sanghelios gets temporary 50% decrease in population, but manufacturing implements of war is much faster.
Great Schism: "The Great Schism is upon us. The unbreakable Covenant Writ of Union has been split asunder. This is the end of the Ninth, and final, Age."
- Covenant factions all receive a solid negative relationship bonus.
- (Tying in with my sub-faction idea, you’d get a solid relationship bonus with the UNSC)
Peace Conference at Ealen IV: Disruption of peace talks at Ealen IV have united the factions against the NCA (+ Relationship bonuses across factions)
Peace Conference at Biko: The disruption of the peace talks at Biko, and the silence of the UNSC embassy has degraded relations (-Relationship bonus across factions)
Jiralhanae raids: The Jiralhanae launch raids against your colonies (Covenant militia as well as economic downturn)
Unggoy disobedience: Unggoy protests escalate across our core worlds (slows economy, population decreases).
