Sand
Loose ground that falls when nothing holds it up. Melt any kind of sand in a smelter and you get glass.
Each kind of world has its own sand, the way each has its own wood. Every one of them falls, which is how you tell it's sand.
| Sand | Found on |
|---|---|
| Sand | Beaches of temperate, arid and ocean worlds |
| Rust Sand | Arid worlds |
| Ash Sand | Scorched worlds |
| Bone Sand | Frozen worlds |
| Regolith | Airless worlds. It's what a world with no weather has instead of sand. |
Glass
Any sand smelts into one Glass. Green worlds have sand on their beaches, so glass is a reason to go to the coast.
