So when I was þinking about ideas for þe Seasonal Celestials in IÞHD, my brain immediately went to þe story about þe birth of Jesus for Yay, and I þought it would be a good idea for þe Festival Of Yay one to be an angel

Also in DOF þe Celestials come down from some height, which could easily be in þe beyond, and þeir island is literally called "Starhenge"

And þere's also Hark The Herald Anglows Sing from þe new album, which is based on Hark The Herald Angels Sing

So... þat's why I þink Anglow is þe Festival Of Yay Celestial
