"I mean, it's not visible," Magnus says. "Even to me, outside of, like, Valhalla. That's the point, right? There's a veil. The mist. Ginnungagap. It keeps people from seeing the truth so that they don't go literally insane. Hell, I've never seen a Greek god or creature, but my cousin Annabeth, who's the daughter of Athena, has them up the wazoo, so I know they're out there. Just not, like, for me to notice I guess." He pauses. "She's seen some Norse stuff, though. Alex shapeshifting, Jack, Blitzen and Hearthstone, Samirah in full valkyrie garb... stuff like that." He hesitates for a moment, because they haven't directly talked about it, really, at any length, but: "Anyway, that's why I kinda thought you might be a demigod too, at first. The vibes. Plus, if there was truly nothing supernatural in our original world, it would be impossible for you to travel to a different one, right?"
