Opening the world

• Recipe of the Ember Heart (Matrix Workbench, after the World 1 boss (Spore Queen) is defeated): 1 Queen Core, 8 Sporite, 16 Spores.
• Rite: Set it down within 3 blocks of lava, with at least 4 Ashrock around it. See The way into each world.
• Arrival: a Threshold platform at the centre of your group's parcel. The boss arena is 160 blocks south (positive Z).

Terrain

Cave-heavy terrain (vanilla caves template) from y -64 to y 128, with lava instead of water as the default fluid. Ashrock and Ember Stone everywhere.

Block	Type	Drops
Ashrock	Stone (pickaxe)	itself
Ember Stone	Light level 13	itself
Giant Vein	Giant ore (pickaxe, correct tool needed)	Giant Ore
Blazing Rock Ore	Ore (pickaxe, correct tool needed)	Blazing Rock

The rule: Heat

The heat gauge goes from 0 to 100 and is updated once per second.

• In water: -2 per second.
• Near lava (within 3 blocks horizontally, 2 vertically): +1 per second.
• Below y 40, away from lava: +0.5 per second.
• At or above y 40, away from lava: -1 per second.
• Thermal armor: each piece cuts the gain by 12.5%, so the full set halves it. Survivor-class gear also helps.
• Hits: each Rock Salamander hit adds 6 heat.
• Thresholds: 50 gives Hunger II, 75 adds Mining Fatigue I, 100 deals 1 fire damage per second.
• Cooling Water: -50 heat. Ice Bread halves heat gain for 5 minutes.

Creatures

Creatures spawn naturally in the world (regular ones in groups of 1 to 3, swarms in groups of 2 to 4, elites alone and rarer) and from spawners in combat structures. See the Bestiary for all fifty.
