Returning from a mission into the early past, the Federation temporal vessel, the USS Pocket Watch returns to the year 2410. A band of rebel Klingons lie in wait, waiting for their next prey. They attack the temporal vessel, still vulnerable after exiting the time stream. The battle is one-sided, weapons and shields are still offline.
The Tipler cylinder is activated and they find themselves above Earth, but not the planet they know.
These events start off in the year 2410 in the Star Trek Online universe. Enjoy!
