Cutting through the middle of the Southwestern Island is the Kaeyale River. The crystal clear waters of the river flow deep and fast in many places, making passage difficult unless one can find one of the few bridges over the water. In other places the meandering course of the river has left behind oxbow lakes and odd islands, many of which are home to naiads or half-submerged ruins. It is surprisingly common to find mysterious temples and altars along the banks of the river, some of which appear to be abandoned. There are others, however, which have obviously been hurriedly vacated in anticipation of an intruder, making it impossible for anyone to know quite what these places of worship are for.
