Axum Bacterial Culture

Name	Biomes	Description
Acidic Raion Pouch		Gelatinous pouch full of weak acid with properties useful in fabrication. Pops if punctured — drops are time-limited.
Advanced Battery		Solid-state, high-capacity battery with a silver-carbon anode. Lasts roughly 3x as long as a Basic Battery. "Battery better."
Advanced Wiring Kit		Specialized wiring for sensitive electronics. Do not examine closely. No user comprehensible parts inside.
Atacamite		Copper-arsenic ore with a bright turquoise streak. Locked deep enough that you will likely need a Sonic Resonator to break the harder deposits.
Axum Bacterial Culture		Live alien bacterial sample. The biological key to the Metal Farm — without it, you cannot automate metal extraction.
Basic Battery		Portable energy supply. Replace often. The universal power input for every handheld tool.
Biofuel Block		Compressed biofuel block. Burns in the Bioreactor for the highest sustained indoor power output in the game.
Celestine		Pale crystalline mineral ore, strontium-bearing. The Karakorum tier gate — most mid-game tech chains pass through it.
Conduit Crystal		Rare crystalline conductor that grows on rock walls and cliff faces. Arguably the rarest early-game material — you will spend a full play session hunting your first stack.
Copper		Cu. Element 29. The basic conductor for nearly every early-game electronic recipe.
Copper Ingot		Compressed copper ingot.
Copper Wire		Conductive wire for basic electrical work. The most-reused intermediate in the entire crafting tree.
Coral Shavings		Fine coral shavings harvested from broken coral. Used in specialized recipes.
Crab Feces		Excretion of large crab fauna; surprisingly high organic content. Yes, this is a real crafting resource.
Creature Enamel		Hard biological material harvested from the tooth clusters at the base of Needler Mango plants. Sharp on the harvest.
Dedicated Core		A discrete microprocessor to control complex electronic systems. Can sustain basic AI functions, in the same way an iron lung can sustain a person.
Enameled Glass		Reinforced glass. Designed to withstand greater levels of barometric pressure.
Entangled Power Cell		Ultra-high-capacity solid state mobile power source. Exploits phase conjugation in gold-sputtered optical fibers for quantum advantage.
Fiber		Organic fiber. Closer to plastic or latex than cellulose. The cloth-equivalent of SN2 crafting.
Fiber Mesh		Strong mesh of plastic fiber. Resembles vinyl.
Fibrous Pulp		Soft plant fiber, harvested by hand. The bulk-feedstock material for almost every fabric/water/food chain.
Germanium Ingot		Compressed germanium ingot, refined from silver or lead.
Glass		Aligned quartz crystal. Hard, clear, tough — and the universal window/hatch material.
Gold		Au. Element 79. Used in advanced electronics for its corrosion resistance and conductivity.
Gold Ingot		Compressed gold ingot.
Grease		Fatty soap and mineral oil. Multiple applications.
Lead		Pb. Element 82. Dense metal for shielding and weights.
Lithium		Li. Element 3. Reactive metal used in high-density alloys.
Lucifer Rotsac		Bioluminescent rotting plant sac. Pops on contact. Glows blue in the dark.
Mangalloy Ingot		Manganese-iron alloy ingot. Required to bootstrap automated metal harvesting.
Metal Salvage		Debris from a human habitat or vehicle. Easily converted into raw materials in a Fabricator.
Mild Acid		Mild raion-derived acid. Used in processor chains and biolab work.
Necrolei Cyst		Biological cyst harvested from Necrolei formations — large purple weed-like organisms anchored to the seafloor.
Pent		Pentagonal mineral chunk. Sparse documentation — may be a placeholder name pre-patch.
Plasteel Ingot		Titanium-lithium composite ingot. The pressure-grade alloy used for deep-tier air tanks.
Power Cell		High-capacity mobile power source. For large structures or vehicles.
Quartz		Silicon Dioxide (SiO₂). For silica glass and optical memory. Often makes up most of a planet's crust.
Rubber		Flexible, tough insulator derived from biopolymers. Squeak-rubber, technically.
Salt		NaCl. Halite. Culinary and sanitation applications.
Salvaged Titanium		Crudely convert salvage into raw Titanium. The fastest Titanium source in the first hour.
Silver		Ag. Element 47. Excellent conductor. Applications in computing, medicine, and nanotech.
Silver Ingot		Compressed silver ingot.
Strong Acid		Concentrated acid, very dangerous. Used as a metal cleaner and catalyst for fabricating advanced electronics.
Strontium		Refined strontium, processed from Celestine. The Modification Station unlock material.
Sulfur		S. Element 16. Yellow crystalline non-metal.
System Chip		A self-contained system-on-a-chip built around a microcontroller. Compact, energy-efficient mobile computer.
Titanium		Ti. Element 22. Ideal for underwater construction — the backbone of nearly every building and tool recipe in the game.
Titanium Ingot		Compressed titanium ingot. Compact storage and a precondition for almost every late-game tool.
Troilite		Iron-sulfide mineral. Dark metallic sulfide. The deepest 'final' mineral most players unlock.
Wiring Kit		Conductors, insulators and harnesses for basic electrical work.
