Hydrothermal Spire

Hydrothermal Spires are tall, conical geologic formations that emit heat. They are predominantly found throughout the Thermal Spires Biome but can also be located in various other biomes to a lesser degree.
Appearance
Hydrothermal Spires are characterized by their tall, conical shape with a hole at the top. This opening constantly emits a black, smog-like substance, similar to real-life Black Smokers. Additionally, a yellow sap-like substance can be seen oozing from the top of each spire.
Colonies of Tree Spires Purple Coral and Glowing Coral Shelves, which typically grow on Tree Spires, can often be observed growing on Hydrothermal Spires near the border of the Tree Spires Biome, as well as in cave systems below said biome.
Databank Entry
![]()
These chimney-shaped structures are formed from dissolved minerals pushed upwards through the planet’s crust. The presence of metal sulfides gives the escaping material its dark, opaque appearance.
Aquatic life found in proximity may have evolved adaptations to the presence of these toxic compounds.
Assessment: Long term exposure to geothermal emissions may pose a risk to human health.
