The Crimson Straits is a passage separating the mainland Arjin from the island of Winterweald. The straits connect the Crags with the Blood Sea and form a large bay that is somewhat sheltered from the raging weathers of the seas. It gets its name from the reddish waters of the straits, caused by excess iron-oxide in the sediments of the sea, stirred by the strong currents. During winter and for a large part of late fall and early spring, the straits are frozen solid, allowing passage by foot. It's by no means a comfortable journey, as the moving waters cause the ice sheet to crack, shift and move. This makes the sheet more akin to a rocky mountain with hills and crevices moreso than flat ice.
