The Fira functioned as the age-old weapon of the Selkath fighters from the Order of Shasa found on the planet called Manaan. This curved sword, the Fira, could cause serious injuries, with each blade being individually crafted by a member of the Order.
To create their Fira sword, those in the Order of Shasa needed to use metals recovered from the ruins of a kolto harvester situated within the Hrakert Rift. Because the harvester's outer shell held cortosis ore, the resulting Fira blade became resistant to a lightsaber. Due to the need to mold the cortosis metal using the intense heat from underwater volcanic vents, the process of making the Fira was both hazardous and lengthy.
