The idea behind layers is to provide a rich map environment for heroes to act in. One where they might use magic to change the precipitation on nearby tiles, or where their magical power might depend on how proficient they are at drawing it from the terrain.

Map layers also map neatly onto Godot's TileMap, which has built-in layer support.
