Belonging to the Haemonculi caste, the mad scientist and flesh crafting Lords of Pain, Skrillex is a master of biotechnology, cybernetics, wetware programming, mind uploading, genetic engineering, etc, etc, etc. Born to a Drukhari archon and her favorite male wych, Skrillex grew up in the lap of luxury along with a brood of siblings. It was once a mere medic, tending to siblings that barely survived the arena. Thinking itself safe, Skrillex grew complacent. But its parents all pitted them against each other, and the few favored siblings that Skrillex allied itself (often with bringing each other to new heights of ecstasy), soon died prematurely at the claws of their rival family members. Sometimes via assassinations, sometimes in fights in the arena, under the cold uncaring gaze of their genetic donors.

With cold calculating fury, Skrillex dispatched each and every single one of its rivals, using them for for experiments and vivisections, done to slake zir thirst into knowledge of Drukhari anatomy.

After studying at the base of Vlokarion's twitching spinal cords, it paid for its tutoring by paralyzing its own genetic donors to Vlokarion as raw resources. Of course, Skrillex kept the originals, having sent Vlokarion, clones.

It's parents have been converted into all forms of horror and living weapons, its mother into a Talos Pain Engine, its father into a Cronos Pain Engine.

Skrillex has vowed to do better then its genetic donors, in rearing its own creations. Some are regular standard Trueborn, others are more....esoteric. Creatures born in frames of biometal. Each of its offspring is doted upon, but of course, its own creations must have their own knife edge's honed. Its own little knives are set to battle against each other, but Skrillex well-learned in the resurrection arts, calls backs its deceased young from oblivion's maw.

It's creations will never know the pain of loss, never know the pain of death destroying treasured possessions. This Skrillex has vowed.

Now if only some of them will stop being so stupid.

In an endless search for knowledge and sensory curiosity, Skrillex uploads zir mind to various bodies, many of whom are genetically or/and cybernetically altered.

Zir current favorite flesh puppet are numerous torsos sewn together into a centipede, scuttling around on numerous hand-feet. Failed underlings are killed, minds transferred to a new body, and their old bodies added to the evergrowing frankensteinian creation. Skrillex is fond of mocking his underlings by wearing their old bodies as new appendages. Also fond of sending out his minions to collect new specimens and pitting them against zir rival's killteams in wargames.

Desperate drukhari will often come to zir for medical treatment and the debt binds them to their new master, they are then sent out into battle to repay zir. But they usually fall in battle, and need to revived via clone growth in the vats. This is not cheap and the cycle of debt, failure to repay and death starts anew.

After Night Flayer brings home a cult of worshipful Adeptus Mechanicus, Skrillex is exasperated. It's torn between filthly mon'keigh wanting to contaminate its labs, but also! free minions/test subjects. Also they worship some of its favored biomech creations with sacred rituals of maintenance. Night Flayer has trained them well, and they free up resources. . Clearly, they admire the work of their betters. One of the hereteks is like "what if i give you my torso and you give me some sweet sweet cybernetics" and skrillex is like* No* because it only wants drukhari flesh as part of its torso segments.

For webway's sake, its not aiming to devolve.

New specimens, bioengineering new creatures, obedient minions.

Minions failing to retrieve new specimens, bodies ending up marred, archons.
