He conveys this.

"They can be any size. I just need something with an opening and any object to activate it. Choose something subtle, that no one will think is a key."

"....okay, we own a park, let's do it there. You need the address?"

"I can also pull up a picture," he says once he's conveyed this.

"A picture should be enough."

Here is satellite imagery of the park!

"I'm going there now."

And Grilbek teleports-

-to the park.

Aitim is rushing over but not there yet.

That's fine. They claim to own the park. Grilbek finds something that looks suitably door-like, and starts casting.

He's not alone. He can feel them with him. It's disconcerting, given that the gods have never paid him personal attention before. They could stand to be less intrusive, really, it's like having someone breathing down his neck.

- and elsewhere, where several wizards, an Amentan, and a mimir await, Arcadia's sky begins to change. It darkens, in a way that it never has before.

The (remaining) wizards are perplexed! (Curious, with a hint of fear, they start theorizing.)

"Why is the sky doing that?" she whispers to Truth.

"-that's Celestian. The god that used to be Celestian. It's- helping, with portal things. Making it so time is the same in both worlds.

I could say more about that but it could- be a lot, if I do that. Might burn me out."

"Oh, no, don't do that, that's enough. I didn't know that was a risk with you..."

"It's not usually, I would have said. Gods are really big, and this one is really close and is doing lots of things...the portal is almost ready now. It just needs a key."

"A key?"

"A key, like your blue hair dye. Every portal has a key that opens it, which is decided when the portal is made. That's why yours is so surprising- your portal must have been made for you. One of the gods must have done it, but- checking who isn't really safe, for me. Sorry."

She reaches into her pocket for her bottle of dye.

"-is that how you came here?"

Daernir finds everything that's happening right now unspeakably cool. He really wishes he had an eidetic memory so he could remember all this exactly.

"I had it with me when I went to school but it's just normal blue food coloring, I don't know why it would do that."

Well they have a button they can press to find out, don't they.

"Why would it do that?"

"---a god definitely made the portal that brought you here, just like there are gods helping us make this one. I can't find out who exactly, or why, without risking burnout but- Celestian helped bring you here, Lintalai."

"- well, I really appreciate that, Celestian," she says vaguely to the sky. "What do I do with this to use it as a key -"

-she hears a sound as though someone is knocking very lightly next to her.
