The Cloud Crystal is a rare and enchanting gem that originates from the Crystal Hills in the Nima Province within the Kami Concord, situated in the northern parts of the Lunora continent. These transparent blue gems possess an inherent power to manipulate gravity, allowing even the smallest fragment to influence the surrounding gravitational forces. Objects near the crystal can hover, as it can both pull and push gravity in its immediate vicinity. Cloud Crystals are discovered both underground and atop the majestic mountains of the region, making them a sought-after resource.

Originally, Cloud Crystals were utilized in the construction of grand monuments during the early eras of the Nagan Empire. However, following the Lunora Civil War and the establishment of the Kami Concord, a group known as the "Hill Union" emerged and successfully gained complete control over the mining operations in the region. With their influence, the Cloud Crystals began to be exported across the world, attracting the attention of various factions and kingdoms.

One such kingdom that has shown immense interest in the Cloud Crystals is the Vache Kingdom, renowned for its advancements in arcane technology. They have harnessed the power of these crystals for their airship variants, utilizing the gravity-manipulating properties to enhance their airship's maneuverability and control.

On its own, a Cloud Crystal can be used as a focus to cast the powerful spell Reverse Gravity. By channeling the crystal's energy, the wielder can manipulate gravity in a localized area, causing objects and creatures to experience a reversal in gravitational forces.

The Cloud Crystal possesses two charges, which replenish at the break of each dawn. This allows the wielder to tap into the crystal's power multiple times before it needs to regain its energy. The charges can be expended to activate the gravity-manipulating effect of the crystal or to cast spells or abilities that interact with gravity-based mechanics.

Whether in the hands of an adventurer seeking to defy the laws of physics or a kingdom aspiring to soar through the skies, the Cloud Crystal stands as a testament to the harmonious blend of natural wonders and arcane ingenuity.
