These are traveling spirit dates they can be found in the sky discord server or @thatskygamecompany on Instagram (or on my tumblr or this book)!
Dates are in the photo
The traveling sprits are from older seasons that have come back. They are randomly selected and only 2 per month!They last for 3 days and can give you "ascension wings", hairs, capes, pants, and instruments as well! You can pick up the "ascension wings" in eden.
