Hrucium, a substance employed within the realm of heavy industry, exhibited instability subsequent to its utilization. Its release transpired as a consequence of a malfunction at Waste Canister Delivery Port 84-D-21, situated within the Desrini District of Coruscant. Notably, the isotope designated as hrucium-5 possessed a heightened level of toxicity. In the era of the Cold War, a chemical transport vessel experienced a catastrophic incident, resulting in the discharge of substantial amounts of hrucium-5 onto the surface of a moon. This event inflicted harm upon the indigenous fauna and compelled the Arcona individual named Senaru to solicit external assistance in an effort to safeguard both his community and their native planet.
