Blackwood
A cursed spinning wheel found on the outskirts of the settlement was broken and burned, but the ashes wouldn’t dissipate in the weather and no grass grew near it. The next week, the inventors sought to research the wood to maybe weaponize it. Within the first month, their primitive weaponry of spears and arrowheads were ingrained with the cursed wood to have more potent and deadly effects than their mundane counterparts. Such weapons were called Blackwood weapons. These are unique to Concordia.
