Jot down the plot and the basic elements you want your game to have.
Make a portfolio on your vision of the game.
Take a look at it and delete everything you borrowed from bigname medieval/fantasy games like Skyrim, The Witcher, Dragon Age etc.
Get people fired up to help you work on this.
Dont work in a standalone engine you barely understand. Concider making it a mod of something.
Be prepared to work on it for the next half decade or longer.
Quote: "-How do I complete such a massive task?"
Make it less massive.

-How would I make a cave system? How do I plan something like this?"
A cave system is just a bunch of models that tile well together. Thats really it. Any freelance artist should be able to do that for you. Shop around!
Or buy
this.

Concidering that you want it to be massive and you assume that you would suffice as the only level designer...
Well. Lets assume you guys really work hard on it and lets assume that your programmer and your model people are ace at what they are doing. 3 years for you to achieve the necessary excellency to do something one can concider massive. A really long time to make the necessary levels. Ages for your lonely programmer to get all the games logic and scripts up and running. Dah! lets just be optimistic and say 5 to 10 years. Also scratch the other jobs part.
