Leystones are a mysterious magical rock found in Vespirian. The samples we've recovered reveal that they are very vibrant and colorful. Huge amounts of magical aura radiates out from them. They appear to be the only item that can keep large masses of land coalesced during a Shift. All large Fragments appear to have a significant Leystone buried somewhere near the center.
It is known that some Vespic tribes carry a small Leystone with them. This allows them to live a nomadic lifestyle among the chaos of Vespic Shifts in relative safety. However, the smaller size of these Leystones limits the size of the territory they can hold together.
