'''Vulcanus''' is a hot volcanic [[planet]] with mountainous volcanoes, rivers of lava, plains of ash, and sulfuric acid geysers.

It is home to [[Demolisher|demolishers]]{{SA}}, a large boss‐like [[Enemies|enemy]] that defends its territory. There's no [[pollution]] on Vulcanus.

[[Planet discovery Vulcanus (research)]] is required to travel to the planet.

== Biomes ==
Vulcanus has three distinct biomes.
* '''Ashlands''' are plateaus speckled with sparse vegetation and deposits of [[coal]]. They are home to leafless [[ashland tree|alien trees]], some of which may be on fire and will spawn flames temporarily if felled. They are relatively free of cliffs and lava, making them ideal for building.
* '''Lava basins''' are filled with winding lava rivers. Within them are deposits of [[tungsten ore]]{{SA}}, which can only be mined using the big mining drill.
* '''Mountains''' are large volcanoes, covered in cliffs and with a large lava pool at their center. They are home to [[sulfuric acid]] geysers and [[calcite]]{{SA}}. 

== Demolisher territories ==
[[File:Demolisher entity.png|thumb|250px|right|Demolisher patrolling.]]
Native to Vulcanus are the giant centipede-like enemies known as "[[Enemies#Demolishers|demolishers]]".

Demolishers have well-defined territories. On the map, these territories are outlined by an opaque, bright red line and the inside is marked by diagonal, translucent, red lines. Only one demolisher will spawn per territory, and the territories themselves do not overlap. However, they are tightly packed, as they follow a Voronoi-like pattern. At the start of the game, only Vulcanus' starting area is not inside a demolisher's territory.

When left alone, a demolisher will patrol the border of its territory. However, if players build inside of a demolisher's territory, it will soon make a beeline towards these buildings with the intent of destroying them. Building inside of a demolisher's territory is therefore extremely risky and dangerous.

The death of a demolisher is permanent, as they only spawn during world generation. Likewise, upon the death of a demolisher, its territory permanently becomes free for the player to use, as other demolishers will not try to expand their territories.

== Access to basic resources ==

* [[Water]] can be obtained via [[acid neutralisation]] and [[steam condensation]]
* [[Stone]] is a byproduct of processing [[lava]] into molten iron/copper.
* [[Iron ore]] is only available in limited quantities from mining volcanic [[rock]], but [[iron plate]] and [[concrete]] may be obtained from [[molten iron]]
* [[Copper ore]] is only available in limited quantities from mining volcanic [[rock]], but [[copper plate]] may be obtained from [[molten copper]].
* [[Coal]] can be mined from patches on the surface as normal.
* [[Crude oil]] is not available, but [[heavy oil]] can be obtained via [[simple coal liquefaction]]. Heavy oil can then be cracked into light oil and petroleum. Once metallurgic science is produced and a stockpile of heavy oil built up, this can be switched to regular [[coal liquefaction]].
* [[Wood]] cannot be obtained, but [[medium electric pole]]s can be constructed using the small amount of ores available. Note that this can soft-lock players that did not unlock the research.

=== Power production ===

[[Solar panel]]s on Vulcanus give 4× the power they would on Nauvis. [[Acid neutralization]] generates 500°C steam, which can be fed through [[steam turbine]]s to generate electricity. The calcite processing technology does not actually unlock steam turbines, so [[Nuclear power (research)|Nuclear power]] or [[Heating tower]]s must be researched first, on [[Nauvis]] or [[Gleba]] respectively. If this is not done, [[steam engine]]s can be used instead (which generate less power for the same steam).

== Space routes ==
[[Vulcanus]] is connected to 2 other planets: [[Nauvis]] and [[Gleba]]{{SA}}.

== Trivia ==
* In mythology, Vulcanus (also spelt Vulcan), is the Roman god of fire, metalworking, and the forge.
* The planet's design, with lava, volcanoes, and sulfur, is based on [https://en.wikipedia.org/wiki/Lava_planet lava planets].
