The hezrou dwells in the vast Abyssal swamps, mires, and waterways, equally at home on land and in the water. The presence of a hezrou has an obvious effect on the nearby flora and water, causing plant life to twist and knurl and infusing water with a foul odor and brackish taste-signs much easier to spot on the Material Plane than the Abyss. Long exposure to this corruption can cause vile transformations and hideous deformities. Often, entire backwater communities of deformed mutants owe their twisted countenances not as much to incest and poor breeding as they do to a hezrou's proximity.
