Columnis

Columnis is a plane completely covered by forests of hexagon-prism glass crystals, criss-crossing and falling and leaning on each other. Under this maze of glass are various ecosystems, such as gravel deserts and tidepools.

Fauna
The plane would seem sparsely populated, when, in fact, it is. It is filled with some populations of wade-deer, tidal wildebeest, and crystal-buffalo, who eat the anemones that populate the tidepools on the ground. There are crystal-jackals, who stalk around and eat either the deer, some anemones, and the carcasses of other species. Crystal-bears eat similarly to the crystal-jackals, but consume crystal jackals too. Finally, there are the apex predators - crystal wurms. These creatures claw their way through the crystals, creating tunnels which seem like good nesting habitat until the wurm comes down and eats the nesting creature.

Flora
The plane does not have much variety of plant life with some types of algae that live on the bottom regions of the columns and lichen that grows on the upper regions.

Geography
The plane has three major biomes: crystals, tidepools, and gravel deserts. It is very difficult to map Columnis, as it has measurements in miles in all three dimensions.
