Avoid Being Loki'd With This Handy Guide to the God of Mischief and His Disney+ Show

Loki picks up shortly after the events of Endgame, as the God of Mischief is arrested for "crimes against the sacred timeline." But what exactly is the "sacred timeline" and why is it so important? In the comics, the term "sacred timeline" is used by Clan Askani, a group of mutants dedicated to fighting Apocalypse while upholding the beliefs of the X-Men. Much like the TVA, Clan Askani time travels when necessary to preserve the sanctity of the timeline.

The MCU has previously toyed with the idea of a "sacred timeline" with the Endgame time heist. When explaining why she can't give Hulk the Time Stone, the Ancient One discusses how the Avengers could accidentally alter time, resulting in the "main" line splintering off into new timelines.
