Wave-spire

A wave-spire is geological wonder unique to the planet Anok. Spanning miles in height, wave-spires bridge the planet’s upper crust with the one below it, from below appearing as gigantic pillars crossing land and sky. Spires are riddled with lava tubes and steam vents, providing a subterranean network of vertical tunnels and caves.

The inside of a wave-spire presents a completely vertical environment, from which Nokkian life evolved. Active steam vents provide regular water and the outer expanses receive several hours of strong sunlight a day.
