When Damar dies and Ziyal lives a string of events is touched off that causes a very different timeline to unfold. The major changes begin when the Borg, during their disastrous war with Species 8472, look to establish a new branch of the Collective in the Alpha Quadrant. They start by assimilating the Federation transport vessel carrying Gul Dukat, who becomes the new Borg King!
This is a plot bunny I've had running around in my head for awhile now. It is based upon the idea of the Butterfly effect, initially small changes can trigger major events down the road. Please give me feedback.
