The Rune of the Moon is symbolized by a lesser-than sign and is associated with false hope and paralysis of thought. It is connected to Kreth, the god of the moon, false visions, and deceit.
Sylvie researched the Rune of the Moon while the party was in Verrow’s Span during a time of escalating urgency due to the arrival of refugees from Dolm’s Break. This led to an attack by the Askavir, a giant bird believed to be Tlellic’s mount, familiar, or avatar. The party confronted the creature, and Sylvie sensed an aura of Splendor magic from the fallen Askavir, reminiscent of divine power. In her attempt to Siphon Essence from the Askavir's heart, she experienced an overwhelming connection to the Rune, which helped her understand its implications regarding their struggles against false hope and despair.
