Lunastra was the planet 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.
