K, the Seltorians were the most trusted of the subject races in the Tholians' home galaxy which they ruled. They were allowed to maintain their own fleet in order to pacify the other subject races, however, unbeknownst to the Tholians they had built up a secret combat fleet and overthrew the Tholians forcing them to flee their home galaxy - leading to the Holdfast and the 312th battle fleet being in our galaxy - they bassically just took the place of the Tholians and became just as despotic. They're, in essence, a race of giant cockroaches and as the Klingons found out they breed just as fast. They realised that some Tholians had fled the destruction and sent out the Seltorian Tribunal fleets to track them down and one group made it to our galaxy and finding the Holdfast allied themselves to the Klingons to destroy the Tholians. They set up camp in Klingon territory and pursued a war with the Tholians for several years until the ISC arriveed. The ISC launched a single invasion of Tholian territory and were soundly whooped. They concluded that the Seltorians were the problem and eradicated their base, the remaining ships fled to the Klingons who took the oppurtunity to destroy them once and for all. Obviuously there will be other Seltorian fleets out there searching for the Tholian survivors but it is unlikely they'll come to the milky way anytime soon. Oh the Seltorians had a weird 'webbreaker' as their main heavy weapon but it was kinda lame and ineffective against the webcaster. Did I miss anything Desty?
