Discovered: 1704 by James Crewton

Type: Heavy metallic mineral

Location: Exclusive to the deepest regions of the Grand Harbor seafloor

Crewtonium is a dark, rust-textured metal discovered by industrial pioneer James Crewton, founder of the Grand Harbor Oil Company (GHOC). The mineral is remarkably dense, far heavier than iron or steel, and excretes a viscous black oil from its surface. Crewton first observed this phenomenon while studying deep-sea formations near Grand Harbor, leading to one of the most influential discoveries in Ironcliff’s history. What makes Crewtonium exceptional is its unique reaction to environmental conditions. When exposed to sub-zero temperatures, salt water, and extreme pressure, the mineral rapidly produces high-grade crude oil. While oil can still be produced under normal conditions, it occurs at a far slower rate. The GHOC developed specialized extraction pods that enclose Crewtonium clusters on the seafloor, injecting cold sea water and increasing internal pressure to maximize oil output. The refined oil, known for its high purity and explosive potential, is used to power nearly every engine in Ironcliff, from automobiles to massive freighters. It serves as the nation’s primary export, driving Ironcliff’s economy and fueling its rise as an industrial superpower. Crewtonium deposits are impossible to locate using standard detection equipment, making the GHOC’s monopoly absolute. Only the Oil Company possesses the knowledge of the metal’s true locations and extraction methods. Despite its economic importance, Crewtonium’s constant oil seepage has caused significant marine pollution, darkening the waters of Grand Harbor and surrounding coasts. Among the people of Ironcliff, Crewtonium is viewed as both a miracle and a curse, a national treasure that binds the country to the GHOC’s control. Many believe the government should regulate or distribute access to prevent the GHOC from manipulating oil prices, but attempts to challenge their authority are swiftly dismantled by both political and corporate power.
