Kalendrite

Kalendrite is a fictional mineral that appears in the tabletop role-playing game Dungeons & Dragons, specifically within the setting of Eberron. It is a type of crystal known for its luminous properties and its association with dreams and prophecy. Kalendrite is often described as having a pale blue or violet hue and is said to glow with an inner light, particularly when exposed to moonlight.

In the lore of Eberron, kalendrite is believed to form in caves and underground locations where residual magical energies are strong. It is particularly associated with the Plane of Dreams, also known as Xoriat. The mineral is highly sought after by various factions and individuals within the Eberron setting, including seers, wizards, and those seeking to harness its dream-influencing capabilities. Alchemists and artificers sometimes use kalendrite in the creation of potions and enchanted items, believing it can enhance clarity of thought or imbue objects with prophetic qualities.

While not a material with inherent combat abilities, kalendrite's value lies in its mystical and arcane applications. It is often found in ancient ruins or guarded by creatures sensitive to its ethereal energies. Its presence can indicate areas of significant magical residue or connections to other planes of existence. The rarity and unique properties of kalendrite make it a valuable commodity and a frequent plot device in adventures set in the Eberron world.
