Once all the data from their scouting teams was analyzed and they had a full measure of what awaited them, approximately half the fleet decided that they wanted no part of an invasion that seemed doomed from the get-go! They began to unofficially call themselves Sav'm (as in "Save them,” referring to both saving themselves and us humans), and worked toward the goal of a peaceful, non-confrontational integration on our world, sticking to the shadows to avoid discovery and gathering resources quietly. The remainder of the fleet, now calling themselves Kyll'al (as in "Kill 'em all, let Zred'Gaz sort 'em out!"), refuse to back-off of the original plan; to subjugate and/or destroy the human race and loot the goodies after. This has led to both sides often engaging in armed actions against one another, with both looking to gain total control over the fleet to determine the next official course of action.
The Zyn generally have 4 arms, 2 legs and one head and range in height from 1/2” to 4”. They have an exoskeleton protecting them from harm, to which they attach extra plating or equipment often based upon mission needs or their particular Corps assignment, such as the Sniper Corps camo gear, the Medic Corps kits and packs or the Sergeant Corps gruff demeanor. The Zyn are also deceptively strong for their size, as well.
