The razing of Exegol, also referred to as the assault on Exegol, transpired from 3 ABY to 4 ABY. It was executed by the Schism Imperial in an effort to contest the authority of Emperor Palpatine. They did this by launching an offensive against the Sith Citadel located on Exegol, the repository of his most valuable artifacts and classified information. This offensive represented the Schism and Vader's most daring act of defiance against Palpatine's dominion.
The initial allusion to the assault on Exegol surfaced within the promotional material for Darth Vader (2020) 46, serving as an enticing preview of the events within that particular issue. The capitalization of the event's name was subsequently validated in the promotional text for Darth Vader (2020) 47.
