If you go through the portals with their respective anomalies you can examine them for different text. But it just seems to be a hot/cold thing that leads to the portals. Other than that they don’t seem to do anything.
What a great way to celebrate a 10 year anniversary. That was such a nostalgia trip.
What the heck. Got the key from the onnet cliffs. Go to use it on a chest and it dissapears!
I think something similar happened to me. I got all of the keys posted in the other thread + the one from the worm things in december yet there's still a locked chest I have no key for.
