2026 Deities & Demons Masquerade Ball & Oct Full Moon #297
DEITIES & DEMONS MASQUERADE BALL
October Full Moon Gathering
Ceremony • Music • Art • Fire • Masquerade • Community
Journey to the Chapel of Sacred Mirrors for the Deities & Demons Masquerade Ball, a special October Full Moon Gathering celebrating the mysterious, the mythic, and the transformative.
The evening begins with a Full Moon Ceremony led by Alex Grey & Allyson Grey, followed by a night of music, visionary art, fire performance, and revelry throughout the CoSM grounds.
As the veil between worlds grows thin and the season turns toward darkness, we gather in costume to embody the divine and the demonic, the celestial and the chthonic, and the many faces that live between.
Come dressed to impress and be with us for one of CoSM’s most otherworldly nights of the year.
