Should the PCs manage to intercept all three bombs and/or catch the bomber in the act, Founder's Day will still go forward as planned by its organizers and the Investors Master Mind. The Zenk assassin is very patient and will wait with his bead on the targets air limo and still attempt to kill him.

This is where each referee has a choice; they can modify the adventure to allow the PCs to catch everyone involved or allow the plot to succeed in killing the politician and Dak Dollo being appointed to the Finance Commitee. The Investor's master mind will go on to more plots and could become a long running shadowy foil in the background of the campaign.

The events of Founder's Day; bomb plots, sabotage plots, and riots will likely cause the Council of Worlds to adjourn the session without a final vote on the bill. Even if the assassination does not go forward another plot to kill the chief politician could during the recess. Dak Dollo will almost certainly be put on the Finance Committee if a vacancy on it opens up suddenly. During the new session he'll be able to tie up the bill or pull its teeth.

Consequences for the Conspirators
The Zenk participants will either get off through the activities of highly paid lawyers or through escaping and disappearing.
The FFF and SDC members who are captured will likely end up in jail for their activities. Some of them may harbor bitterness against the PCs and will likely make cryptic threats.
The ARP members will, at most, get a slap on the wrist for interfering with an arrest but despite any other charges they will get off. Anna Che will go on to denounce the organization the PCs work for in the strongest terms even suggesting that the events of Founder's Day were a government plot.
The Investor is pretty much teflon; nothing should end up sticking to him.
Dak Dollo stands to lose everything if he's caught. In the aftermath, evidence that fingers him as the master mind will be found on his computer and it will be very convincing. He'll go on about a shadowy figure and wild stories but no one will buy them. In the end he'll commit suicide in prison. That is if he's caught.
