The ancient Thallonian Empire has collapsed, throwing an entire sector of the galaxy into chaos and unrest. Billions of sentient beings are faced with starvation, warfare, and worse. Faced with a tragedy of interstellar proportions, Starfleet assembles a new, handpicked crew to help where it can and report what it finds. Captain Mackenzie Calhoun, recommended by Jean-Luc Picard himself, takes command of the U.S.S. Excalibur, which is manned by Starfleet's best and brightest, including some old friends from Star TreK: The Next Generation and some of the most dynamic new characters ever to boldly go where no one has gone before!
