In the Abyssal Release ( 7777 DE - 8777 DE ) , the primordials sought methods to combat the escalating numbers of demons ravaging the realms of Piranoth's Steps. Recognizing insects as rapidly multiplying organisms, the primordial lord Beldileck fashioned a sentient praying mantis the stature of a warhorse. Christened Thri-kreen, it became the progenitor of a novel species.
In the war against the demons, the thri-kreen proved invaluable in keeping their distance, showering their demonic foes while hardier elements moved in for the kill. Owing to their natural camouflage, these thri-kreen units were consummate ambushers. Although sentient, the insectoid mindset lingered, leading to prolonged hunts and units vanishing for months until their desire to hunt was satiated. Unsurprisingly, both the demons and the Covenant captured some of these creatures. They became the prototypes for their own works of Creation. Those that fell into the hands of the demons, with extensive exposure to the Threads of Damnation, warped into more wicked and destructive entities, becoming the first Chasme.
There were three paths for those captured by the Covenant. Some were relocated to the worlds of the Mortal Systems, while others were advanced upon, at least according to Semuanya and his Auhtai creations. When Asmodeus became a Fallen Angel, a thri-kreen unit very loyal to him accompanied their great leader to Nessus. Akin to those trapped on the worlds of Piranoth's Steps, the individuals who went with Asmodeus were transformed by the fabric of their new home worlds, becoming the Gelugon.
