Verity is just walking down a street, on her way back home, when she almost loses her balance. The floor shifts under her, she feels like she’s moving but it’s not along any of the three typical dimensions. She closes her eyes to avoid the dizzying visuals and, when she opens them again, she can’t recognise her surroundings.
She must have fainted and hit her head. Or be dreaming. No amount of reading will have prepared her for this if she’s actually been isekai’d somewhere. That just doesn’t happen! (Except in stories but no breaking the fourth wall if there is one, it’s not helpful to think about either way.)
Well, if she’s hallucinating, someone will probably notice and help her back in the real world; if she’s dreaming, she ought to have some fun; and if this is real -it’s probably not but- she should get her bearings. So… she can examine her surroundings?
