This is what I've come up with so far. I don't have any details about the size of the castle but extrapolating from the descrition it sounds like it might be small to medium size. I am not the best castle creator so this one is more "representational" than photo realistic.
A castle with a wall in a semi oval shape off the side of a mountain to the north. with a village named "Fenton" to the south with about ten farms and a few other buildings. One road leading up from the village to the castle. Could a person do this for free to make a group of people happy?
