The South Tack (sometimes known as the Inner Sea South Tack) is one of the two major sea trade routes of the Inner Sea. Like its northern counterpart, it runs along the southern coast of the Inner Sea. It begins in Katapesh and heads north from there to Sothis in Osirion before turning west while hugging Garund's southern coast all the way through the Arch of Aroden and into the Arcadian Ocean. From there it turns south and ends at the Rahadoumi capital of Azir.
