Shrieker (Eldar)
From Warhammer 40k - Lexicanum
Shriekers are feral bat-like Chaotic Eldar Mutants who dwell on Belial IV.[1]
Their ancestors were once normal Eldar who lived upon the Crone World, but a hundred generations of living within the Eye of Terror led the Shriekers to their current state. They now live in communal nests that lie high in Belial IV's ruins and hunt while letting loose the shrieks that give them their name.[1]
Upon encountering the creatures, the Apothecary Arrian Zorzi noted that the Shriekers were among the few stable Eldar ab-strains he had seen, although their genetic code was degraded to the point of indecipherability.
