- "We're talking about the Apocalypse, damnit! It's what the Alsakan priest warned us about."
- —Ussej Padric Bac to Darth Plagueis just before the latter's death[src]
The Apocalypse was a galaxy-ending event beginning in 41 BBY with the death of Darth Plagueis and the ascension of his apprentice, the Dark Lord, as Dark Lord of the Sith. According to the Prophecy of the Chosen One, the Dark Lord and the Apocalypse could only be stopped by the Chosen One, whom the Ophuchi Clan believed to be Annikin Skywalker.
