Lunastra was the planetoid within the Supernal Triad that represented the moon within the triumvirate of the night. While dominant, it once heralded Ourania's influence over the triad. Its surface was comprised of red caverns and depressions.
On Phaestian 13, 427 AF, the planet collapsed, along with its companions Noxtra and Somnustra, during the Eternal Night, forming a silvery ring through the skies of Achaea.
Imbued with lunar majesty, its tidal effect is encapsulated in its namesake mystical card.
