Leechmen are a hematophageous race of degenerated elves that live in the Leechdens region. Their oily, black skin, double-lidded eyes, and gills make them among the least recognizable as having once been elves. Their horribly betoothed maws render them unable to speak in any intelligible language, but a surprisingly-detailed written tradition catalogs every important event for each tribe dating back to its inception—primarily, these "manuscripts" detail the methods of hunting and consumption of various marine and land-dwelling creatures.
The Leechmen are only found in Effelai.
