The boggy, swamp planet Dagobah is the principal planet in the star system of the same name. Although explored, Dagobah remains sparsely populated because of its inhospitable climate and generally unpleasant surroundings. Constantly shrouded in mist and strangled by dense vegetation, the planet is the home to numerous animal life, including dangerous flying predators. The Jedi Master Yoda also makes his home and hideout there and is the only resident of notoriety.
When the evil Emperor Palpatine ordered the Jedi Knights erased from the galaxy, Yoda went into deep hiding there, using its natural defenses and the power of the Force to discourage visitors. It was not until near the end of his days, at the arrival of Luke Skywalker, that the 800 year old Yoda would have a purposeful visitor.
Dagobah is totally without spaceports nor any other modern technological convenience. It has been considered a haunted planet due to its history with the dark side of the Force and an evil group of Dark Jedi that terrorized it and the neighboring Sluis sector during the Clone Wars.
