Sesharrim

The planet Sesharrim is the homeworld of the Gaouls, which is orbited by at least two moons. It is an Earth-like planet with a breathable atmosphere, but has a distinct otherworldness feeling given by its red oceans and red skies.

Most of the planet's landmasses are insular, forming archipelagos in the shallow seas. The many reeves and islands are surrounded by forests of hydrogen-trees: life forms which grow on the shallow waters, somewhat like mangroves, and whose yellow blisters store hydrogen in a way that the tree can violently explode when bumped into.
