Mū (Location)

Mū (ムウ) is an earth-like planet that lies in another dimension. It is the homeworld of the Rinnegan summonings.

Description
Mū is a planet whose surface is covered by a vast island continent and an even larger ocean. The surface of the continent consists mainly of tropical rainforests, but also of wide plains and mountains. The landscape is intersected by numerous rivers that form high and shallow waterfalls. Wide sandy beaches form the edge of the continent.

In the vicinity of this planet there is a huge gas planet with a ring, which (especially at night) is clearly visible in the sky.

In the dimension that houses the planet Mū, there seem to be completely different laws of nature as in the universe known to us. The planet has a warm climate all year round, is inhabited by apparently immortal beings and is not exposed to any external or internal dangers. But despite their harmonious homeworld, the Rinnegan summonings are capable fighters.

The planet itself can usually only be reached through Rinnegan-based Space-Time Ninjutsu.

History
Although Mū was never permanently settled by an intelligent species, traces of civilization (houses) can be found there. These structures were once built by Hagoromo Ōtsutsuki with the Creation of All Things Technique after he awakened the Rinnegan, mastered the Animal Path and got there via Space-Time Ninjutsu. Hagoromo provided the bodies of the apparently immortal summonings living there with Black Receivers in order to use these creatures more effectively in combat. During his lifetime, he occasionally used the planet as a place to stay.

Since Madara Uchiha never used the Animal Path and Nagato could not use a Space-Time Ninjutsu with the Rinnegan, none of them found out about the existence of this planet. After Sasuke Uchiha awakened the Rinnegan and did research on the history of the Ōtsutsuki Clan, he also came to this planet.

Murasaki Uchiha uses the buildings on this planet as a repository for Black Receivers, which she uses in surprise attacks with Jikūkan Hikō.
