Warning! Spoilers for Crimson Reign #3 ahead!
There are many powerful Force users in the Star Wars universe, but very few are as powerful as Jedi Master Yoda. Order 66 saw the purging of Jedi across the galaxy, and those who survived were forced into hiding and exile. Some Jedi managed to avoid the bloodshed by toning down their connection to the Force, but in the case of the all-powerful Yoda, simply toning down his Force connection wasn't enough to hide from the Sith. Therefore, he had to try a different approach.
Yoda took refuge on the swamp planet Dagobah. Fans of the series know that this is where Luke Skywalker first met Yoda and began his Jedi training. It's been suggested that Yoda chose Dagobah because of his past and the planet's connection to the Dark side of the Force could outshine his own, but until recently, this was mostly just a theory.

The Archivist says that Dagobah is incredibly strong in the Force, describing it as a "shining light in the galaxy, bright enough to outshine even Yoda's luminous spirit."

The Jedi's feats earned him a reputation across the galaxy, yet the full extent of Yoda's prowess with the Force remains unknown.
