In a region located beyond Fulgora and Nauvis lies a large asteroid field. This field is extremely scarse in carbonic asteroids, as most of them were absorbed by one of the two planets found here during its formation period.
In this region you'll find planets Muria and Paracelsin, the worlds of lead and zinc, also known as

THE SPELTER TWINS

For more info on the planets, check their specific pages!
