That’s the question writer Andrew Steven Harris and artists Gordon Purcell, Bob Almond, and Terry Pallot explored in Star Trek: The Last Generation, a five-issue IDW miniseries that tied in with Pocket Books’ Myriad Universe trilogy.

The murder of President Ra-ghoratreii spawns an alternate timeline in which Starfleet no longer exists, the Federation is crumbling and the Klingons have conquered Earth, with Worf overseeing its subjugation. Jean-Luc Picard now leads a desperate resistance movement to liberate mankind.
