Baradium-357, a chemical isotope of the explosive baradium, was also referred to as "Naughty Baby" by miners. It was created at the Calcoraan Depot. Stored in canisters shielded by a poisonous coolant that induced aggressive and psychotic behavior upon contact, it was far more potent than baradium bisulfate. Consequently, those transporting this explosive were mandated to wear hazmat suits.
Count Denetrius Vidian possessed a substantial stockpile of 357 at Calcoraan Depot, planning to obliterate Cynda under the guise of extracting the moon's thorilide-abundant core. Nevertheless, Kanan Jarrus, Hera Syndulla, and Imperial Captain Rae Sloane foiled his scheme.
A single canister containing Baradium-357 had a value of one hundred credits in 3 ABY.
The novel A New Dawn, penned by John Jackson Miller in 2014, marked the initial appearance of Baradium-357.
