I've got this idea for a setting that I really like. Its sort of like an "Alice in Wonderland" place, where a person in our real world can accidentally fall through a "rabbit hole" and end up there. This place is made of several layers, that one must qualify in order to go deeper. In each level, time passes differently. So, 5 days on the first level is only 5 minutes in the real world, but 5 years on the second level. Each level also has its own distinct qualities, and well I guess you could say personality. Also, not everyone there is human, for example a squirrel could have fallen through and now you have a walking talking squirrel in this land. There is of course a lot more to it, but I think the idea is creative and it could be an excellent setting for a series of short stories I believe I'd enjoy writing. The possibilities are really endless with it. Now, here is my problem, I can't figure out what this setting is. Like what kind of place is this, is it an extremely advanced spaceship that created portals spread throughout Earth? Is it a parallel universe connected through black-holes? (Does that work?) Is it some kind of heaven that was created at the beginning of the world? Maybe a magician from this strange world cast a spell that somehow opened up the portals. Hmm... just writing this post has given me some ideas, but the problem is that I don't want anything utterly ridiculous. While I am writing fiction, I would like for it to be conceivable, if that makes sense. So... I just want to hear what you think. Is it important that I explain my setting at all? Should I just go with creativity and not worry too much if its believable?
