The Channel of Assarania, also known as the Assaranyan Channel, is an ancient, manmade channel in Arrida. It connects the Constant Sea to the Sea of Blood.
It has been dug in ancient times by the old Assaranians (people probably based on the Ancient Egyptians). There isn't much traffic on the Channel.
The Channel is probably based on the Canal of the Pharaohs, an Ancient Egyptian version of the Suez Canal.
