Everyone, while confused as hell, decided to play along for now, and quickly decided on a fantasy world with swords and magic.
"Great, a classic. That makes things easy since I don't have to explain the details of the world's functionality quite as in depth. So I assume you all know what role's you each want to play as? Go ahead and write them down anywhere on the walls using your finger. Oh, and please keep them generalized as best as you can. A detail here and there is ok, but do not make an entire background or some complex life story please. Just a sentance or 2 is perfect. Oh, and no talking or making prepared pairings, such as husband and wife. But making that as future goal is ok, to an extent." The 4 of them went over to a seperate wall and began writing out their generalized character.
Will- I want to be a knight or hero who will one day marry the princess and is popular with the kingdom's ladies.
Chriatina- I want to be the talented, personal maid of some high ranking noble family, who is also secretly their extremely skilled combatant/bodyguard.
Tom- I want to be the world's strongest sorcerer, capable of using all forms of magic.
Rachel- I want to be The Royal Princess. Who has both extraordinary looks, and flawless skills at charming her targets into serving her. This is because she is secretly half-succubus, which is a secret only known by her immediate family and a select few individuals.
Diana watched her 4 players decide their roles, eagerly waiting to spring her first trick upon them. It didnt take long, after a few minutes, each of them had finished and walked back to the room's center, as their character entry vanished into the wall. The moment everyone was in place, Diana let her "big reveal" happen.
"Perfect! Now then, let's draw for role selection. Who is going first?" Asked Diana as if it was natural to be expected to do this. The looks on their faces after hearing that made her internally squeal in delight. This is what she lives for. That look of sudden shock and disbelief, followed by wave after wave of anxiety and uneasiness as what she said was played over and over in their heads.
