I couldn't find good pictures of a peninsula, but I just grabbed some water pictures I thought were cool.

The Bolchester Skerry is the peninsula, owned by Grateford.

There are also the Four Oceans, the North, South, East, and West. Also known as the Faerie, Asrai, Seelie, and Unseelie Oceans- since all religions start with the Fae in Riatos.
