The dragon uses Spellcasting.

For their lairs, moonstone dragons look for places kissed by the moon; lonely peaks, forest clearings, and placid lakes are among their favorite sites. Their whimsical nature makes them more likely than other dragons to establish multiple lairs even at a young age. They link their scattered sites with magic portals, often splitting their time between the Feywild, the Material Plane, and the Ethereal Plane. The challenge rating of a legendary moonstone dragon increases by 1 when it's encountered in its lair.

On initiative count 20 (losing initiative ties), the dragon can take one of the following lair actions; the dragon can't take the same lair action two rounds in a row:

• Banish into Dream: The dragon targets a creature it can see within 120 feet of it and attempts to send that creature to a dream plane. The target must succeed on a DC 15 Charisma saving throw or be banished to a harmless demiplane until initiative count 20 on the next round. While there, the target is stunned. When the effect ends, the target reappears in the space it left or in the nearest unoccupied space.

• Compulsive Dance: The dragon targets a creature it can see in its lair, and a merry waltz begins to play that only the target can hear. The target must succeed on a DC 15 Intelligence saving throw or dance until initiative count 20 on the following round. The dancing creature is incapacitated and must use all its movement to dance.

• Disorienting Visions: Disorienting illusory images flit through the dragon's lair. Each creature in the lair must succeed on a DC 20 Wisdom saving throw or have disadvantage on ability checks until initiative count 20 on the following round.

The region surrounding a legendary moonstone dragon's lair is altered by the dragon's magic, creating one or more of the following effects:

• Dream Communication: Whenever a creature that can understand a language sleeps or enters a state of trance or reverie within 6 miles of the dragon's lair, the dragon can establish telepathic contact with that creature and converse with it in its dreams. The creature remembers its conversation with the dragon upon waking.

• Planar Transition: The veil between planes is thinned near a moonstone dragon's lair. Various portals link the Material Plane, the Feywild, and the Border Ethereal within 6 miles of the lair. Creatures can pass through a portal in either direction by spending 5 feet of movement.

If the dragon dies, any portals near the lair close immediately

Often, a moonstone dragon's lair is not a single location, but rather a collection of personally significant places spread out across multiple planes of existence and connected through portals under the dragon's control. A lair might include a secluded grove on the Material Plane, a well-protected tower in the Feywild, and even a hidden corner of the Ethereal Plane. Moonstone dragons often use locations in the Feywild as their primary residences, locations on the Material Plane for entertaining guests, and locations on the Ethereal Plane for storage. Occasionally, though, a whimsical moonstone dragon delights in shaking things up, insisting that visitors come to the Border Ethereal for a meeting or sleeping in the middle of a heavily trafficked forest on the Material Plane. Moonstone dragons navigate their multiplanar lairs by opening portals between planes at will. They sometimes forget to close those portals, allowing the inhabitants of one plane to wander into others.

Moonstone dragons prefer silver, platinum, and mithral to copper and gold, and white or silvery gems to more colorful ones. Some are simply uninterested in treasures made of what they consider inferior metals, but others actively dislike copper and gold creations and consider them aesthetically offensive. People who mistakenly offer these metals to the wrong moonstone dragon sometimes wake to find all their silver—and memory of the past few days—missing. In addition to their strong preference for certain metals, many moonstone dragons seek out artworks and relics with unique, whimsical, or absurd designs. The more fanciful an item's form is, the better.
