Grids are levels underground or inside buildings. They are used for caves, sewers, catacombs, temples and the like.
Grids are distinguished from terrains by the following features:
- They must be walled around, walls can only be erected on a raster of squares with 5m side length.
- The ground is always flat. You may have several levels, though.
- Grids can only be connected to terrains or other grids by portals.
- Each grid must have exactly one tileset, which specifies the look of ground and walls. It also contains possible features and portal entries you can use with that tileset.
