Maybe i'm not paying attention but they had a key made, and flipping over a temple, and traveling to the temple of realms, i have no idea why. my favorite part about the game is the combat feels like a way more polished version of bloodborne. Story wise last of us is on another level for me.
that was like one small section of Tyr hiding the Tower to jotunheim. nothing really compicated about it.
But yeah, gameplay was great.
