It doesn't seem right to not maintain the tradition of having a thread for each event as it happens. Since no one started an official thread for this leaderboard and the informal thread that was created was closed, I will take the initiative to start a new thread. It's not going to be fancy - I don't have the time and s**** to post pictures of all the milestones and dragons, but here is a summary at least.

Leaderboard 11/19/21 - 11/25/21 (This leaderboard is only 6 days long, while leaderboard events prior to November 2021 were always 7 days long.)

Milestones:
1: mystery chest
2: Pillow Party - decoration that earns leaderboard points
3: 5 Crowns that can be used towards crafting the new Nightmist dragon

Prize Dragon for coming in first or second in your local leaderboard: Daydream Dragon (Fairytale/Pink)

To earn more points, you can breed a Nightmist Dragon (Fairytale/red). Breed this dragon using a combination of Fairytale and red dragons, or, per the pop-up, use red and black.

The accompanying tournament offers the new Cuddle Dragon as a reward. It is Fairytale/Rainbow.
