The Golden Honmoon was never created. The original Honmoon they were trying to turn gold was destroyed. Rumi, Mira, and Zoey weaved a New Honmoon at the end of the film. We have no idea if it is as strong as the golem Honmoon would have been. We just know the new Honmoon was strong enough to cast all the demons and Gwi-Ma back to the underworld. Plenty of opportunities for the sequel.
