Water Crystal (Eufez)

The Water Crystal is located in the Sunken Ruins, a place typically inhabited by mermaids. The crystal is not protected by the mermaids, but they rather live among it.

Elemental Crisis
The "Hole of Sorrows" is a sinkhole in the Lykion Desert. Some speculate that the dimming of the crystals has resulted in an increase in seismic activity, which has led to a large number of sinkholes forming specifically in the Lykion desert. The first was the Hole of Sorrows, which was discovered in 1855.

Such sinkholes have continued to occur since then and the rate of occurrence has increased exponentially since the loss of the water crystal. As a result of these sinkholes, the soil has become highly unstable and is known to be a potential hazard for humans making crops difficult to grow.
