Guild Wars 2

I was replaying PonR and had to afk in frond of the abbadon statue, so I started to dance. right before I got out of my chair my character fell into the downed state. Nothing around to hit me, Marjory was still talking. I stood up and danced again just to see what would happen and I went down again. Is this an easter egg reference to the final mission in Night Fall?

It is. People discovered it when they first introduced the Priory basement in s2e5’s Hidden Arcana.

Or it could be the god’s response to the quality of your dancing. Try it in front of a statue of Kormir. Her kind nature accompanied by a handy blindfold ensure an enthusiastic reception when you cut a rug. (Assuming you aren’t one of the characters who also makes a bunch of weird grunts and noises when they dance).
