The Winter Festival - previously 'Christmas Festival' before it was changed to be more inclusive - is an annual festival that takes place in the Grand Avenue of Heldencoast. A white winter is a common concept in media, yet the hot climate doesn't permit anything of the sort in Heldencoast.
The festival was made years ago by accident. A local minor villain, Frost's Bite, was in an intense battle with a hero. He created snow-generation machines to create a weather phenomena, locking down streets with snow and ice that the local populace were unprepared for. When faceplanted into a snowbank during the fight he heard a young child open the door to his home and call it a 'Christmas Miracle', and he gave up up his villainous ways.
...or so he says. Cynics think that after the fight with all the news coverage he realized he could make more money by setting up this annual festival than from his petty theft. From then on every year for about a two week time 'ol Frosty freezes over the Grand Avenue, stalls are set up, large decorations of all denominations are erected and the locals can enjoy a winter wonderland.
Coats, skates, and other winter paraphernalia are available for rent.
