They perform some more magic tests and run out of mana and recover mana and perform more tests and a second sleepover could be fun but it's decided that people can do coordinated tests in their own places and there is not actually a need for them to all be in the same place. The Maxwells' driver takes Jess home (and Maya, too, if she prefers that to staying with the Maxwells but they assure her she's welcome to stay there), then takes Sadde, Theo, and Tyler to the Farron residence, where Sadde prefers to be dropped—he'll go to his place by public transportation, he'd like to talk to the—twins?—yes, thank you, it was a pleasure meeting you.
"And regardless these ghosts are probably a card, yeah? Not all cards can talk."
"… I mean I don't know how Voice would work on those cards but okay, could be the reason."
"Are we intending to wait for another? Because if we wait, we might get another."
"Another ghost? I'm not sure it's that useful, we're trying to find the card here and—this does not look like any cards we know, does it...? Illusion I don't think works like this."
Theo shrugs. "I don't have a clear idea of how illusion works. Unless it's the Dream, maybe I'm – or one of us, is – actually asleep right now?"
"The Dream is supposed to give you dreams of your desires, or prophetic ones, neither of which is... relevant, here."
"… It's probably not relevant, unless this is for some reason a prophetic dream of this scenario. Which it probably isn't, and doesn't really matter if it is." Pause. "Okay, so. Illusion? How does it work instead, I'm not really sure how this differs."
"Shows people their deepest desires, and different things to different people, and isn't solid like that."
"… Okay, I feel kinda bad for not knowing that if you already know the cards in that much detail."
She peers at her notes. "I don't think any of these cards directly do compulsion, do they? So we could do something, like, by the sun and the moon I compel you to talk? We haven't played around with phrasing too much, that could work."
So Maya tries! She charges two pieces of paper, one with 'Sun' and one with 'Moon', and then says, "By the Sun and the Moon, I compel you to talk!"
"Bring them with? Or try touching them, see if they were just menacing us or are actually able to do damage?"
