Gillmin

​friendly aquatic species from the Vargen Swampland ​gills​​ ​glowing beads​ ​can communicate.​
  The Gillmin are a species of small, friendly aquatic humanoids that inhabit the Vargen Swampland. They have a fish-like appearance, with skin covered in scales and webbed hands and feet. Their large black eyes are a prominent feature, as are the glowing beads that adorn their bodies in different patterns. These beads can be lit up on command, and are used by the Gillmin to communicate with one another. Although they have gills, the Gillmin are also capable of breathing air for short periods of time. They have no spoken language, relying instead on their glowing beads to convey information.
