Hughes, the DM: You’ve made it to Truth. It looks at you, smiling, and says, ‘If you want Al’s body back, you have to give something up.’
Ed, a gnomish wizard: I. I offer… I offer my magic.
Hughes: Truth nods. Your sacrifice is accepted. You wake up in the real world again, now powerless, but your brother has his body back.
Al, also a gnomish wizard: Aw bro that’s so sweet of you omg
Roy, a human sorceror: lol but now you’re useless
Ed: Fuck. How do I do magic now?
Hughes: well, you can’t be a wizard anymore. But you could always be a cleric and dedicate yourself to a god - if you follow their precepts, they’ll grant you powers.
