Now, my grandma happens to own a castle, il Castello di Riva. It was the residence of her family, and I used to go there each and every summer when I was a kid. This probably has something to do with my addiction to fantasy gaming and literature. By the way, I'm thinking to use the real castle floorplans to model the ruins above the dungeons of Zordaz. If you look at this map you will find that it's composed by five main buildings: the lord's manor (incorporating the gate), three small towers and a big 100' high tower in the northern corner (this also has a small dungeon right under). The green region indicates the old moat. The castle is located on the top of a ravine, with a river flowing dozens feet below; I'm thinking of relocating it at the top of a cliff, kinda like Camelot in the tv series of the same name.
I imagine several caverns opening directly on the cliff, one of them possibly housing an ancient red dragon. Now, back to the castle itself, I find it sexy because it adds several new exciting possibilities. For example, I always wandered what was beneath the well in the middle of the garden when I was a kid. I guess it's time to find out myself.
