The Gmmosanders are a race of bipedal creatures which share characteristics with both birds and amphibians. Like birds they are warm blooded, and have feather-like structures on their heads, arms, and tails. Like Amphibians, they spend the first part of their lives in water.
Gmmosanders have a society based around loose clan affiliations, which often leads to small wars or infighting. They have been known to band together to repel common threats.
