My thought process for Ethos stems from String theory, making ethos a sort of chaotic string, that can be refined into a usable stable string.

I am still considering how ethos should be used, and the restrictions with the different ways of using it.

Ethos comes from beyond the Geminis Veil, it is theorized that the hole we make in the veil to harvest Ethos can maybe be used as a way to leave.

Strong wills help to reveal the Veil and allow those within Geminis to pull Ethos from it.

Ethos is an un-refined fuel source. It can be used raw, but is very taxing on the body. Blood contains life Ethos, bones generate the life Ethos. Increasing heartrate increases Ethos saturation in the body.
