It's a fantasy role-playing game.

DM: You are Tiberius Stormwind, a dragonborn sorcerer . You are the member of the famous group of adventurers. Previously, On Vax's request, Gilmore procures a favor for him with the Lyceum. Vax also purchases three enchanted daggers, presumably as a gift for Kynan Leore.
DM: You're working in the workshop, you're eating, you guys are going to Gilmore's. All right. So as this is happening, Tiberius, you make your way over to the Alabaster Lyceum. You come up to the front main area of the structure itself. It's an arcane college. You make your way to the front clerk, who looks up to you, a nice young fellow, looks like he's trying to work through his credit in school through his training. He's dressed in the ceremonial robes of somebody who is a student, who is currently stuck with the job of working as a clerk. He's like, "Hi, can I help you?"
Player: Yes, hi, if you do not remember me, I am Tiberius Stormwind, from Draconia. Moreover, Vox Machina, over at Greyskull Keep.
DM: "Where have I heard that--"
Player: Well, we told you multiple times before. We met with you using your sigil of teleport-- it's fine. I've come here on a matter of business anyway, so that's neither here nor there. I was wondering if I may procure an address, or number as it were, for a sigil to Kraghammer. I believe the Thunderbrands would have some facility near theirs or on their own premises where their sigil could be channeled through the Circle of Teleportation spell.
DM: "If you're talking about sigils for teleportation, you would probably have to discuss that with Gatekeeper Xanthas."
Player: Where is he? I thought that was you.
DM: "No. I'm the clerk. I run the front of the-- follow me." And he gets up and leads you further into the structure to the central circular room, the white-marbled room that contains all the doors around, and in the center there is the Traverse Junction. This is the place you guys have stumbled into every single time you've teleported back to Emon. And there you see the elven wizard who you recently bothered naught but maybe five hours ago, who is currently setting up some sheets, comes back. "Oh. Hello, again."
Player: Hi. I'm Tiberius Stormwind, from Draconia. Moreover, Vox Machina over at Greyskull Keep. I was wondering-- and I asked your clerk here because I thought he did what you actually do here-- if I may procure, for coin or perhaps some kind of favor of sorts, the address or number or code or whatever it is that would work for the Kraghammer sigil of my Circle of Teleportation.
DM: "I get an understanding here that you're seeking access to one of our many sigil-based rooms of transference. Those rooms are currently under very protected lock and key, approval by the headmaster Thurmond Adalum himself."
