Hey guys I'm new here! I've unlocked every part of the krypt... Well I thought I had, I was just nosing around in the Kytinn Hive in the part where you do the Amulet puzzle and I paused the game to discover that there's a bit of map still locked, please see the linked image, I can't remember ever getting to the left side where the bridge is, any ideas of how I get there.

Thanks
