The Mezulla River (pronounced meh-ZOO-lah) is a major river in Brightmarch. The tributaries that feed the river begin in the hilly terrain of the Shaushkan Forest before joining in the north then flowing out into the Gulf of Aserdus. Marsh grasses and river mangroves grow along much of the Mezulla, providing both safe refuge to those that wish to remain undetected as well as hiding spots for opportunistic predators.
Electric eels are commonplace in certain parts of the Mezulla River, particularly at its mouth near Dhegata. These eels are far more dangerous their their kin elsewhere in the world, having long ago acquired a far more potent electrical shock through some uncertain means. When agitated they can collectively cause the surrounding river itself to become hazardous, even not particularly near the eels themselves - all who live along or near the Mezulla River know to check the waters before stepping into the river lest they receive an unpleasant or dangerous jolt.
The Rootguard of Xelas patrol parts of the Mezulla's headwaters as part of their defense of the city.
