Does the Castle Ditch fall off as a smaller cascade at the south west end of the island. I saw a picture by F. Kenton Musgrave on the cover of a computer graphics magazine back in the 90s, I think it was called, "Exalted State." I really loved the island. Basically the island gradually rose up from the sea on one side(let's call it the "east") and then dropped off in a big rocky cliff on the "west." I always wanted to make a map based on that island(wanted to call it Promontory Island with Castle Promontorium on the west side. That would fit in beautifully with this idea.
