As for genders, lets see:
Forest: Dryagender, a form of agender connected to an empty forest, Forestgender, a gender related to forests, Earthgender, a gender connected or tied to earth and nature (to be used by non duotheistic pagans, non wiccans, and nature based kintypes), and Ouygender, a gender connected to trees and wood.
Ocean: Hadogender, a gender connected to the deep ocean and eldritch secrets, Aquagender, a gender that changes depending on which type of water you’re near, Gendersea, similar to gendervoid, but related to the ocean, and Hydrogender, a gender which shares qualities with water.
Space: Astralgender, a gender relating to space, Caelgender, a gender aesthetically associated with space, Stargender, the gender of a star, and Astralgendervoid, a gender that is connected to space, stars, and the universe as a whole, vaguely masculine in nature, and has ties to both the feeling of genderless-ness and having indescribable ties to masculinity in a vague sense.
Pronouns:
First of all pronouns =/= gender so you can use any, but here’s some themed pronouns!
@pronouns-archive has an #astronomical, #botanical, and #marine section of nounself pronouns! Tho if you’d like, here’s some emojis that could also work!
Forest: 🌳 and 🌲
Ocean: 🌊, 🐳, 🐋, 🐬, 🐟, 🐠, 🐡, 🦈, 🐙, 🐚, 🦀, 🦐, and 🦑
Space: 🚀,🌌, ☄️, 🌠, 🌃, ⭐, 🌟, and ✨
I hope this was all helpful!
