Giant Leech

Colloquially known as Giant Leeches, Aretis are fearsome maneaters. They can grow up to eighteen feet in length and have membranous wings which, although they are flightless, they are thought to use to propel themselves at great spead through the swamps of their homes. They have two to three rows of in-turned teeth which they use to latch onto their prey, who they will drain of liquid until death.

Aretis are thought to be native to the swamps of Ymmeon, although youngsters have been known to appear in the rivers of Eradona and the swamps of Agranica from time to time, perhaps suggesting some natural migration through the oceans. This may imply that they also make up part of Aira's 'Serpent' population.
