"Let's proceed on then," says Captain Yot. Alia and Jeremo shoot you choice glares. Burnie happily keeps the course and you arrive on time at the conference.
The conference is a success, but the image of those innocent Klingons dying gives you nightmares. You decide to resign from Starfleet. After all, wasn't your mission to save lives? You settle on Starbase 16 as a janitor. Then the Borg come. The cube was successful in killing all the Klingons, and managed to assimilate lots of military knowledge from Captain Kapult. Soon Starbase 16 is blown up. YOU DIE! In fact, the whole Klingon Empire and 90% of the Federation die before the Borg can be stopped. The rest of the fallen Federation are easy pickings for the Dominion.
