🌌 Stardust Dragon – Forgotten Realms Lore

Origin:
Stardust Dragon is said to be born from the Astral Sea itself, a celestial wyrm forged from the remnants of falling stars during the Dawn Cataclysm. When gods reshaped the planes, a fragment of divine essence collided with a comet, giving birth to this dragon—a guardian of cosmic balance.

Role in the Realms:

• It roams the skies above Selûne’s domain, acting as a sentinel against aberrations from the Far Realm.

• Worshippers of Selûne and Mystra see Stardust Dragon as a herald of prophecy and magic.

• Its scales shimmer with constellations, and its breath carries the essence of starlight and pure arcane force.

Personality:

• Aloof yet benevolent, Stardust Dragon despises reckless destruction.

• It often intervenes when mortals tamper with planar boundaries or unleash catastrophic magic.

Adventure Hooks:

• A cult seeks to bind Stardust Dragon to power an astral weapon.

• The dragon’s lair, a floating crystal citadel in the Astral Plane, holds secrets of spellfire and ancient star maps.

• A prophecy claims Stardust Dragon will descend during the next Tears of Selûne meteor shower.
