Stacks of ingots
Borinium ingots were a type of currency that possessed great value. It was about a handspan in length, possessing six sides and a vaguely golden color, although its precise composition is unknown. When dormant, Karack metallites greatly resembled these ingots. Natira attempted to pawn a shipment of metallites off on Scorpius by claiming they were actually the borinium ingots they resembled.
