Hello,
I am currently making a rather large fictional universe on a made up planet and I’m having an issue coming up with a reasonable origin story for a certain part of my land. It is covered in volcanic terrain, lava, harsh rocky surfaces, a volcano, and a lot of burned vegetation/plant life. There are multiple different mutated creatures and a fireproof intelligent species that live there. It is only part of this map I have created (surrounded by desert) and originally I had thought of a meteor shower hitting the area (making it into what it is) but realized that doesn’t make any sense. Anyone have ideas?
