So, I’ve been back into Crota’s End recently to help a friend through their first run, and that was when I saw it.
From the Bridge, if you look up and scope in around the Oversoul, it’s surrounded by floating red blobs!
I thought this was super neat, and a neat bit of foreshadowing for Shadowkeep. Frankly, I can’t believe I never noticed this before.
Makes you think about the origins of the Scarlet Fortress’s builders.
Edit: Here’s some footage my buddy and I took today from the bridge. The proof for all those asking.

Those were always there and I doubt it's foreshadowing. If there is any connection, it's more likely they looked back at the raid and said to themselves "how can we connect some things?".
