It's a fantasy role-playing game.

DM: You are Scanlan Shorthalt, a gnome bard . You are the member of the famous group of adventurers. Previously, The twins have their drinks and wish each other good luck on their separate trials. Her group leaves the tavern, Grog saying goodbye to Vax as the rogue flips him off in true Vax fashion.
DM: You may have even been able to do before you slept the night before, so then you would have all your spells back. So we'll say you did that. So you have an extra Invisibility spell in your Ioun Stone.
Player: And I can store three spells in there, right?
DM: Three spell levels.
Player: Three spell level-- So only one spell at a time?
DM: Or you can do three 1st-level spells.
Player: Oh! Then never mind. I thought it was three different spells. I've already got an extra Lightning Bolt in there. I won't add to it, never mind.
DM: Then yeah, that is a full Ioun Stone. That thing is pulsing with energy and going, "I'm good."
Player: I'm good, didn't understand.
DM: Fair enough. Percy.
