The temple at the center of Lusha’anar was once swallowed by the sea but with the Lunatide Staves the Waterwitches where able to raise it to the surface. The ground around the temple may still hold some remnants of the magic that was employed but I cannot go close enough to take any samples. Close to the temple you should be able to recover some core samples from the sand. With those samples I will be able to make a final determination about the magic that was used here.
