So the events are not explained in-game; they are for the player to stumble across in the initial stages of the campaign.

There are two events:
1) Gongsun Zan Submits
- Requirements: Control Tuyin, Gongsun Clan does not exist
- Reward: Gongsun Zan and White Riders unit
- Reasoning: When Gongsun Zan first rebelled against Liu Yu, it was the latter's goal to beat Gongsun down and force his submission. Liu Yu felt as though the wayward Gongsun Zan could be redeemed and made a subordinate once again. This mission reflects that reality.

2) The Three Brothers
- Requirements: Control Pingyuan, Liu Clan does not exist
- Reward: Liu Bei, Guan Yu, and Zhang Fei
- Reasoning: Until he was executed by Gongsun Zan, there were many powerful gentry, nobles, ministers, and governors that believed Liu Yu should be named Emperor in order to restore the Han. They viewed Emperor Xian as a puppet of Dong Zhuo and, perhaps during that time, an ill-suited leader of the dynasty. If Liu Yu had defeated all his rivals in the north and became a legitimate figure for Han loyalists to rally around, chances are Liu Bei would have thrown in his lot with the winning side.
