Three armed Petharian

After the Petharians joined the Union, they quickly gained a well deserved reputation of being one of the societies most loyal to the Union.

Very few are known to have gone astray, but traditionally when it's discovered that one has done so voluntarily, that individual's family will tear off one of their four arms and declare them dead to all Petharians.

Prior to joining the Union, ocasionally a Pethanian was born with a rare fusing of two of their arms. The individuals with this birth defect normally didn't survive until adulthood.
