Universe 107-LS9
Universe 107-LS9 is the Starfleet designation for the alternate timeline that the crew of the USS Ronin, under Captain Idril Mar encountered on stardate 238403.13 when officers from that universe intentionally used the neutron star Eratis to create a bridge between universes in order to procure manpower and resources with which to repell an impending Gorn attack on Deep Space 17, an attack that would eventually prove to be a catestrophic loss from the Ithassa Fleet in that universe. In the coming months, the Gorn Hegemony and their allies, the Romulan Star Empire, the Cardassian Union, and the Klingon Empire, effected the total destruction of the United Federation of Planets, plummetting the entire Alpha and Beta Quadrants into chaos. Those some powers then turned on each other in order to via for power and territory.
The moment at which Universe 107-LS9 diverged from ours (which Starfleet deems Universe 001-A01) when Lieutenant Commander Idril Mar was killed while chasing after Lietunant Wilde, Danny. Her absence meant that the order to ram the ma:New Orleans class USS Independence into the Gorn flagship at the first Battle of Eratis was never given. Thus the Gorn fleet was never cripled, and a truce was never reached. A small number of inter-universal refugees from this universe have attemted to flee the chaos of their own universe for the relative safety of ours since the fall of the Federation. Most notedly, former Station Commander Danny Wilde, who ultimately met his end on Earth in 2385. The only known native of Universe 107-LS9 who continues to reside in Universe 001-A01 is Jackford Kolk, who escaped Earth after the demise of Wilde and has not been heard from since.
