It's a fantasy role-playing game.

DM: You are Jester Lavorre, a tiefling cleric . You are the member of the famous group of adventurers. Previously, you already vandalized with the Raven's Den and the Hearth of the Allhammer, and decides to skip the Valley Archive of the Cobalt Soul, since it's where Beau and Caleb are training and researching. She also decides against the King's Hall, since there are a lot of guards and it is the center of local law enforcement.
DM: As you approach, this beautiful but small white building is draped in deep blue tapestries, while a reflective mirrored sphere sits atop the roof during the day. I think you've passed by and seen it before when you were traversing the city. Are you going at day or nighttime?
Player: We're checking out during the day, you know, like we're visitors.
DM: Okay. The inside is open archways and floor spaces. They're made available for worship, but also used for meditation. There are a few folks in there that are quietly, eyes closed, taking in the atmosphere of the interior. There's areas for reading and there's areas for napping and sleeping. Of the Bahamut worshiping that goes on in places you've seen on the Menagerie Coast, this one is a little more New Age-y than you're used to. About noonish when you arrive, there is a sermon beginning, where there is the Herald of the House, which is a silver-scaled dragonborn in his older years. He looks very tired and as withered as a dragonborn can through their silver scales. He's in the process of giving this very deeply empowering speech about, "The majesty of Bahamut bestows upon us the knowledge and the grace in which we can be beacons of truth and justice in a world that wishes to swallow all with chaos."
Player: (snoring)
DM: But yeah, the midday stakeout appears to go well. What do you wish to do?
Player: How often does he come back?
DM: He's there most of the day, and in the evening he appears to go nap somewhere within the Platinum House.
Player: And then he gives his sermon during the next day and the next day? We scout it out a couple days in a row to really get the feel for the guards.
DM: Okay, make an investigation check.
Player: With advantage because Nott's helping me?
DM: Sure, sure.
Player: Oh Jesus H. Macy. Nine. Nein!
DM: There's a couple entrances, some hallways.
