Erkii

Erkii is a sub species to Human, but with slight modifications, due to evolutionary tactics. Erkiis hit puberty about 2 years later than humans, inherently dislike loud noises and are less likely to die of illness. The life expectancy of an Erkii is about 97 years and they look 2 years younger than they are, most of the time. Erkiis are nearly extinct, as they were looked down upon by humans. They are taller, lankier, and have higher metabolism than humans. They require more food than Human's do and have a peaceful nature, but will not back down when they need to stand up for their families, friends and countries.

The Start
Erkiis existed for a very long time, since about 1000 years after the Human. They have since evolved into being very human like. Around 300 years ago, Erkiis were being hunted down and killed, leaving them to be nearly extinct, and there are an estimate of just 2 living today. Most were killed in Jagdasian Yimmu-Audal. The only known ones exist in the Huitca Federation today, but there may be unknown ones.

Why Extinction
Humans committed genocide on the Erkiis, in ways that most genocides happen. Telling humans that Erkiis were going to take over them and all those bad things. Most were killed. During the switch to Rathnir more were killed, and during the Coalition War a lot were murdered. As sad as it may be, few Erkiis live on the planet, and there may be more, that we don't know about.
