Unders: A series of dots representing where a passage runs below a higher passage on the map, in maps that portray layered levels. Also useful as secondary roads/trails in terrain maps.
Under: A half-series of dots, used in creating underneath passage junctions that turn within the hex.
Bands: A solid band to create paths, walls, or other linear features. Also useful as main roads in terrain maps.
Band: A solid junction to connect bands. Rotate and stack these in a hex to create branching intersections with bands.
Shaft: An outlined circle representing a shaft leading between levels of the map.
Spiral: An abstract symbol than can represent a spiral staircase or other feature.
Axons: A solid axial band to create walls and other linear features. Functions well as a mid-hex door symbol or demarcator.
