I don't think I have to explain, but a Ouija board is a board with the alphabet, numbers 0-9 and the words yes, no and goodbye written on it. It comes with a planchette to spell out the messages. Participants place their fingers on the planchette, and it is moved about the board to spell out words.
The actual fun comes later when you play Truth or dare? to find out who made it spell "Reinstate Monica Cellio". The game is trademarked by Hasbro, but in exchange they also get the lawsuits from soccer moms because little Timmy is now Valak's free real estate.
Now there is this post-apocalyptic world with magic, swords, sorcerers and dragons. There's also an unhealthy dose of creepypasta injected into it.
In this world, the Ouija board actually works and is able to communicate with things from the other realm. These include deceased people (like XXXTentacion) and, of course, demons. However, I can't understand:
How could a children's toy summon beings that can cause localized hurricanes (Pazuzu) or Belzebub, the severed head of a pig, but with eldritch blast? And where the hell have they been? It's not like there is an actual GOD god in this world to punish them. And it's not like they don't want to cause chaos!
How could demons so powerful, they make the local clergy scream in fear, be dismissed by moving the planchette over the word goodybe, or the act of saying goodybe.
I mean, you're in a predicate where even Dragon Jesus afraid, then say
"Goodybe JoJo"
and the demons be like
"Looks like Team Rocket is blasting off again!"
As they're catapulted back straight into Hell.
Why goodbye? It's not the n-word, it's not even a racial slur, or anything offensive. It doesn't carry any power. Misgendering the demon would have more power! (calling a der a das)
So, those two things (summoning and dismissing) are somehow connected. But I can't figure out the reason behind either. It's clearly not magic, magic is all about either bending the four elements to one's will, or magical sunlight punches here. Yet, there has to be a logical and plausible explanation.
