Femushinmu Planet

The Femushinmu Planet was a planet in which the Yggdrasill Corporation called by the codename Helheim (ヘルヘイム) and was the place where the Corporation discovered the Helheim Forest. It was first thought as an alternate dimension, but was actually an alien planet of the Femushinmu, sentient beings who built their own civilization. As it was where Helheim Forest was discovered, it was the first place where Yggdrasil discovered the Lockseeds.

Known History
The Femushinmu are the native beings of this planet. After the Trial of Helheim, their Woman of the Beginning, the Femushinmu Queen chose his king Rosyuo as their kind's Man of the Beginning.

Rosyuo began converting his people into the forms that can adapt to the forest, Inves. His people started fighting for more power, eventually massacred each other into extinction, leaving the strongest behind. The strongest were given the code name Over Lord Inves by Yggdrasill Corporation's Ryoma Sengoku, and were known to have the ability to control the flora and fauna of the forest.

After noticing a small rift in space, the opportunistic Redyue sent a small seed through it. The seed found its way to Earth and grew up to become a huge tree in Zawame City and was considered as a Holy Tree by it's residents.
