Laufey theory
"Everyone's asking who created the Mask, but nobody's asking the real question: who scattered it? Think about it. By the time Atreus begins searching for the Mask in God of War Ragnarök, its fragments are already scattered across the Nine Realms. That means someone got to them before Odin ever could, and I think that someone was Laufey. Faye spent her entire life fighting Odin. She knew his obsession and understood exactly what he was searching for. So what if she found the Mask first and shattered it before Odin could ever complete it? But what if one fragment didn't scatter? What if it fused to her hand and, instead of taking her to the Light of Alfheim, it pulled her into Everywhen—a place beyond space, beyond time, filled with the bodies of those who came before, every single one of them wearing a Mask. That's when Faye realizes this isn't the only Mask, which suddenly makes her line from the trailer so much more terrifying: 'That Mask... it can't be. If there is another Mask... their path isn't safe.' But here's the clue I think everyone is missing: the cube. Look closely at the trailer. The mysterious gateway is built entirely out of cubes. Phranque is a cube, and the developers have already teased that the cube plays a major role in the story. Then there's Rue. Her magical ribbons aren't just carrying the sword—they're sealing it. And where is the sword? Inside another cube. So what if none of this is a coincidence? What if the Mask doesn't unlock ultimate knowledge, but instead leads you to the gateway? What if the cube isn't just a box, but an ancient prison? The ribbons are the seal. The sword is the key. And Phranque isn't just a companion—he's the guardian standing between every realm and whatever lies beyond that gateway. Which means Faye wasn't just hiding the Mask from Odin. She was stopping him from opening a door that was never meant to be opened. So... am I cooking, or have I completely lost it?"
