In a situation where you don't know where you are, what to do, or how to escape, the best option is to ask someone who does know.
"And that's why I'm counting on you, echidna!!"
"That doesn't matter now, please explain how we got here. I'm sure we all want to know."
"You're wrong!!"
(hello...)
And to prove my point to the forgetful echidna, I took out the straw dolls that greeted me timidly from my all-powerful {"dimensional storage pocket"}.
"Of course it counts, so hurry up and don't leave us in suspense."
After hearing an affirmative response, I stopped shaking Echidna.
"Literary world?"
"?"
(?)
To save time from Echidna's extensive and complex explanation, it can be said in a few words that literary worlds are unfinished works that their writers created by accident.
"How did that happen?"
(yay!)
After being pointed out by Echidna, the straw doll raised its arms cheerfully (adorable).
"So... you mean this is like a pocket dimension inside a book created by a writer's thoughts and dreams?"
"Well, that clears up many things, except for one... How do we get out of here?!"
