Hydrogas is a magically produced, lighter-than-air substance that is highly flammable. Harvested from the floating islands of The Dreadfort, it is one of the most valuable commodities in the modern world, serving as the primary fuel for Airships and a vital reagent in magical experimentation. Hydrogas appears as a translucent, shimmering vapor with a faint green tint and a metallic scent. It possesses several remarkable properties:

Highly combustible when exposed to flame, electrical discharge and it can respond unpredictably to arcane fields and spells. Toxic if inhaled over prolonged periods, leading to symptoms similar to Shard Blight. Because of its magical properties, Hydrogas cannot be synthesized artificially at scale; it must be extracted naturally from shardisite deposits and as a byproduct of Shardisite refinement.

Hydrogas revolutionized travel across the fractured world by making airships possible. Contained within magically reinforced tanks, Hydrogas provides lift and propulsion for vessels of all sizes.

Airships typically mount multiple tanks,, balloons, envelopes or other storage means allowing for redundancy in case of puncture or sabotage. In combat, Hydrogas tanks are a primary vulnerability; a direct hit can result in catastrophic ignition if safeguards fail.

Hydrogas is among the most tightly controlled and lucrative commodities in the world. Access to Hydrogas production is held by those with deep connections to natural shardisite mining and processing and prices are manipulated through national licensing agreements, export tariffs, and privateer enforcement.

Hydrogas is typically sold in:

• Compressed containment tanks.
• Tankered bulk-freighter airships.
• Arcane stasis chambers.

Prices fluctuate dramatically based on political tensions, piracy risks, and supply disruptions. Warlords, pirates, and breakaway nations all seek Hydrogas as a path to power and fortunes rise and fall by controlling its flow.

Due to its magical volatility:

• Ships carrying large quantities of Hydrogas are at constant risk of catastrophic ignition.
• Arcane interference (especially in wild magic zones or near shard-blighted regions) can destabilize Hydrogas tanks.
• Naval powers often employ specialized sharpshooters and mages to target enemy fuel tanks during aerial engagements.

Hydrogas remains both a blessing and a curse, fueling the dreams of conquest even as it whispers the threat of destruction.
