These were revealed with Odin's Sight. Anyone know what they are and how to reach them?
Found these in an area named Perie which is Northeast of Buckingham, in Oxenefordscire.
It's where you fight the legendary wolves.
They're identical to AC Origins Animus Pulse icons and I have never seen them in this game.
I can't find a way to reach them. Found a hidden entrance and a well, but nothing there.
