Korra - Land of Waves and Prisms (LOWAP)
Waves: this is obvious. southern water tribe i mean really. the planet’s full of water and islands.
Prisms: if you shine a light through a prism, what happens? LOTS OF COLOURS. rainbow of colours = rainbow of elements, because you know. avatar. this white light to rainbow thing can also be a different metaphor. the white light going in could be negativity or a bleak life, and then the rainbow it becomes can be positivity. the prism itself would be hope.
Bolin - Land of Clay and Lost Souls (LOCALS)
Clay: Clay comes from the earth??? also really obvious. very earthy sort of planet. lots of rocks and soil.
Lost Souls: this has a lot to do with the heart aspect. heart can also refer to the soul. also i imagine that the planet is just filled with happy little flying spirit thingies and i don’t know maybe Bolin tries to make friends with them while he’s there.
Mako - Land of Smoke and Fauna (LOSAF)
Smoke: fire produces smoke. i was going to use ash, but i tried to refrain from using vowels in the initials.
Fauna: Fauna means something along the lines of “animal kingdom”. i imagine Mako’s planet to look really desolate, but for some reason there’s just animals
Asami - Land of Metal and Dice (LOMAD)
Metal: i imagine Asami’s planet to look kind of industrial considering her father’s profession.
Dice: the light aspect is all about luck. what better represents luck and chance than dice?
there’ll be quests to go with all of this later, but idk yet.
i hope these all make sense ha.
