Description

The power of Moi Freyas drips out like a cloud of ideas. Collecting ideas from every plane and redistributes it in precipitation.

This cloud is thick enough to sail through and can be used to travel through every inner plane. While traveling through this cloud, you aren't bound by matter, moving through the tree as you wish.

Knowledge Fishing

Some diviners will travel through the ethereal plane in attempts to find long forgotten knowledge. Some knowledge of before the starfall can still be found here. But as with all libraries, it is like searching for a needle in a haystack.

Some diviners find magic that their eyes can't handle, transforming into horrible monsters with attempts to infect others with knowledge inconceivable to the living creatures.

Psychopumps

A large community of Sphinx live on the ethereal plane with their occupations as psychopumps. They help the lost dead towards their destination, smelling their destination.

Since sphinx are only to look visibly perceive into the ethereal plane from our world. As such, to communicate to their family members on their plane, they have made a non-verbal language.
(Sphinx is a sign language)
