The serans.

after the event that had griped the galaxy by the reapers. commander sheaperd had ridded the galaxy of the reapers. but after the war there still were home worlds to rebuild, family members to mourn, and planing for the time ahead. the asri and the turians and salrians had started rebuilding the citadel and repairing there worlds. the humans have decided to colonize another world. but the soon found out why a world was abanded for years even decades.
A world know seran, a world long colinized by humans but abaneded for decades becuse of a at the time what was a virus from a unknown elmant that was used during everyday life. the elmant effected only humans becuse of thier long term contact with it. while it is still uknown wath the called it, its name was the seran virus. it changed humans beyond belive. soon there were different types of serans. all deadly in there own right. and the virus gave the serans veins a different color, different strengths, but also weakness. ad attributes that diffrentieated from one to the other.

COBRA
the cobra was one of the first to show up in the virus. it gave the cobra black veins and eyes showings its power with anger. Since it was the first of the virus everyone was unsure if it was an accident or something else. the humans enslaved the cobra people. while there were still human just different in vein color and eye none the less the humans unaffected by the virus would soon find themselves making a crucial mistake. soon the cobra started to evolve new ablitys. evolving a lung-sack like organ in the chest by there heart and soon they were able to spit a tar like substance at there enemy's. and the tar would stick to the opponent and begin to burn flesh. becuse of this new found ability the cobra escaped captifty and escaped to the cold mountins and established life among themselves. But because of this they devolped a weakness. they were so used to the cold that they devolved a emunity to cold which ment that they had a increased weakness to heat rendering them powerless. but the cold made them stronger and increased there powers in extremely cold weather. they were also able to render there enemys in there tar like venom causing them to be stuck to the ground and burn at the same time. but all of these powers and ablitys come at a cost. there greatest strength and weakness is there anger. there anger is what fules them to fight because of a life of enslavement. but the angrear they get the stronger they get but that anger comes at a cost. the bigger there anger the more the blood presure goes up and remember the that the poisin is held in the sack next to the heart and if they get to angry there heart will become filled with there won poisin causing a heart attack. but they are still deadly fighters to fight with. but the cobras were not the only ones.
