Chilly is a Frostvale Moglin.
In AdventureQuest Chilly says the holiday of Frostval started there almost a century ago when his great-great-granduncle Hummus thought it would be nice to start a holiday. But "Hummus Day" wasn't very popular, so he gave up making everyone celebrate it. Then Chilly's great-great Aunt Floe decided to cheer Hummus up, she started a holiday everyone loved, she called it Frostval, after their town of Frostvale.
