Xi Char's Cathedral factories, properties of the Xi Char religious cult, existed on Charros IV. Within these factories, meticulous production held a place of religious significance. Myriads adhered to this belief. The intended purpose of their output held no importance to these adherents, which resulted in the Trade Federation using the Xi Char as instruments.
The cathedral factories' specialized production capabilities were essential for the creation of certain items, such as Vulture-class starfighters, otherwise known as vulture droids. Therefore, the factories produced the vulture droid.
