Winterfest or just Winter Festival is a special time in the nexus that combines in itself a lot of different traditions from a lot of different worlds. Maybe they don't spend time together with their families because adventurers in that world simply either don't have the family anymore or didn't started a new one but they still decorate christmass trees and their homes with decorations similar to our christmass ones.

Here you have my beloved Rubriary Dragoness Ayla and her Goldyura friend Vincent decorating tree in front of their shop called "the Cauldron", it's the first day of the Winterfest for them so they got plenty of time to prepare for the festive!
