Lead the Festive Moa to the two villages, first the one in Zehlon Reach, then the one in Issnur Isles. As you get near to each village, the moa will run off to her chosen dance place. Move alongside the moa and then it is time for you to play some music for her to dance to. Use any of these emote commands: /drum, /flute, /guitar, or /violin, etc. Once the villagers have been cheered up, you can walk back or map travel to the nearest outpost and then go out to talk to the Frost Maiden. After the second village. return to Kamadan and speak to Grandfather Kringle and claim your reward.
