The USS Enterprise-J was a proposed sim and the successor to the USS Intrepid storyline.
The USS Enterprise-J was set in the year 2430, 54 years after the end of the Dominion War. The war severely weakened the Alpha Quadrant, but together, the Federation and its new allies picked up the pieces of what was left in shambles by the Dominion and re-built the once prosperous Alpha Quadrant. However, the Dominion, having re-built its ships and elected a new shapeshifter leader, was again threatening the Alpha Quadrant.
The Enterprise-J was organized in 2007. An extensive website with background info, rules & protocol, and crew bios was published, but it does not appear the sim ever officially launched.
