The Osrisian Tripods (Trionites)

This, is a species i created.
They're simply called "tripods" but to themselves, they're known as "trionites"
They are the second species on Osris-1
(this planet right here)


(The pink, is just to make it more alien-y. I mean ya don't see pink grass everywhere folks)

appearance and behavior:

They were carnivorous creatures, hunting at day and on rare occasions, at night.
As you can clearly see, they have a single hind leg, and two front ones, their skin has a rough, texture similar an elephant.(yet less wrinkly and baggy)
Their skin is colored a dark greyish-blue, almost black, and their eye color depends on gender, for males have a yellow eye color while female's eyes are blue. The newborns on the other hand were born a grey-white color, and would reach maturity at 11 years old. Back in their animalistic days, they were social creatures, travelling in packs of 7 to 9, they roamed freely with no Alpha male or female. They communicated through several cries and gestures.

Evolution and history:

They started out as a multicellular organism with a simple build. Said organism was made of a 2-part body, head, flagella, and eye.
(look familiar?)

This creature roamed around, devouring microbes and minding it's own business, later it evolved into a fish like creature with two vertically placed eyes, a grey color, 2 front fins, and one back fin. It's mouth evolved form a simple hole, to a "+" shaped mouth, with each side containing 2 sharp teeth.
The creature became a predator.

(not pictured)

It then evolved into it's tripodial form, which you read about at the beginning.

However, evolution took it's next step by making them bipedal.
Since it had no other back leg to stand on, it's tail evolved into a new hind leg, as the front legs became arms.
They soon, went tribal, becoming the second dominant species apart from the Primii, (these guys:http://imgur.com/a/8AzLF  ) who were experiencing a civil war, giving the tripods time the advantage to evolve. (the war didn't take millions of years, the Primii noticed the evolution WAAAAYYY before they had the war, but never bothered to interact.)

They later finally met the Primii as a Tribe. The Primii saw them as meek, and an annoyance to their progress, so a long war was sparked.
Many important battles took place:

- The Great Raid (The tripods decided to attack a major Primii village, and steal their supplies. They retreated hours after they set fire to the village, important tripod general was killed tragically) 

- The battle of the seas (The two species crossed paths at the Osrisian seas, and waged another battle, using harpoons, flaming spears and weak, primitive, explosives. No one won.)

- Eastern ambush (When two tripod villages were exchanging goods via trade route, they were ambushed by Primii soldiers. The tripods lost.)

- The final stand (The primii decided to finally wage a full on attack on the main village, which they did. The tripods got ahold of the news, and were prepared to meet them halfway to the village. They met and fought each other for many hours, but the tripods were pushed back to the village, where they surrendered due to a falling number of troops, and other villages already being destroyed.)

The tripods lost the war and were used as slaves, until they rebelled years later.

The two species reached a reluctant truce, and let each other be.
Separately, they proceeded to learn, improve tools, and develop technology.
They both met again once they created great cities, and finally reached true peace. They developed together for many years, and became a space-faring civilization. The Tripods and Primii both colonized the planet's two moons, and a neighboring planet.
They now seek to find new life in the universe.

And that's about it.
