!!! my work-in-progress is set in a tidally-locked watery world. the two main characters have just reached the falloff cliffs where melted (salty) water meets snow-border (mostly pure water, having gone through a cloud cycle).

i'm iffy on my worldbuilding skills, but the image is clear in my mind, so a-writing i must go!! but i can't wait to learn more about that planet :)
