You know what’s wrong with this planet? It’s too hot, and it’s too dry.
We’re practically useless on dry land. Just a lumpy, inert mass in our shriveled stasis. Luckily, you skeletal creatures are 70% water. And you’ve figured out a system for freshwater delivery to make up the difference. That’s very helpful on days when your star is visible through your atmosphere. But we most enjoy days when the liquid in your atmosphere rains from the sky.
