The year is 2409. Over a century has passed since the events of Star Trek: Discovery and thirty years since the events of Star Trek: Nemesis. The Romulan Empire has fractured after the destruction of their homeworld; covert meddling by the Undine and Iconians has forced the Federation and Klingon Empire into war with each other once again; and remnants of the Cassian military and Alpha Strain Jem'Hadar disrupt the peace.
