There are tutorials about that. Somewhere. On this forum.
We had a mini team like this a while ago... >.>What do you want? Fantasy/futuristic/etc?
What about a little girl falls into a well and her leg is broken. While in the well, she discovers a door to another world and take it from there?
Unfortunately, we can't be your inspiration. Story is one of the most important things. Google writing prompts, maybe that will spark you, but "fantasy" is pretty vague. Construct something, a character, a setting, anything to start from, and then maybe I'll see if I can help. But you've really got to take the first step.
