These lands represent the shifting landscape between Aetoria and the lands of the Duiin Si, just beyond the Western Reaches. Here, as the two planes merge, the land is unstable and its mana volatile. Although physical changes are subtle and slow, changes to the flow of mana beneath are erratic, as the leylines twist and tangle. Leylines are occasionally torn apart, their flow shuttered up stream. When this happens, the mana within has nowhere to go and takes form as mana-rich stones that are as unsettled as the process that made them.
