Clutching his head he fell hard, still the sounds of cracks could be heard. Porcelain shattering but more then that, the very sound of a soul breaking appart. They had been building up for months with all the attacks and Xynn couldn’t hold back any longer. Nix ran over but stopped as a gurgling ethereal laugh began to echo around the room.
N:X-Xynn? Are you.... Xynn is that still you?
HAHAHAHAAGUHHUHUHUHUHHHHHHHHH!
The dolls limbs and body began to stretch and elongate as more cracks formed an began to separate revealing a sickly yellow glow. The light itself became fluid, running out from within, twisting his appearance to that of a nightmare gone wrong. Oozing faster and faster the cracks continued to separate turning the normally small doll into a large horror as he stood to his new full height easily a foot taller then Nix. The human backed away as the hunched figure stood and turned. There was one final gut wrenching crack as the eyes and mouth shattered completely reavealing the swirling tormented insides of fused demonic essences in a sick broken grin.
?: Xynn has died and we remain... the purest TRUE SIN BLEEDING FORTH WE ARE CALLED BY YOUR PAIN AND GLORY! IT IS TIME YOU PAYED FOR YOUR OWN SINS HUMAN! LET US ABSOLVE THEM TOGETHER!

So you may remember Xynn(sin) is not an ordinary demon, he is legion he is amalgam he is many. An experiment Nix undertook fusing countless demons of the 7 deadly sins into one being creating Xynn and giving him unprecedented psychic powers. Despite being made of porcelain Xynn is tough, almost impervious to all but the most extreme impacts, he needs to be to contain everything he is. However wear and anger and stress slowly cause tiny cracks to form on his body, the crystals are meant not only to focus his powers but also help keep this in check. He cannot be repaired like the other puppets, he needs to slowly regenerate over time. If he doesn’t get the chance the cracks grow and spread till he looses himself and shatters. All that evil leaks out breaking the body and wearing the pieces and it grows. It is hate and sin, it is a sickness that should never be allowed free. It. Hates. Nix. It seeks to consume the sins of humanity and spread in a vain attempt to separate the screaming interior back into indeviduals. It’s not Xynn this is a different entity and one that Nix cannot control....

So I’ve had this idea stuck in my head for years and when I noticed  felisrandomis doing these hallow commissions I had to take my chance and finally get at least part of this out there. Plus it’s rather fitting for the season don’t you think ;)
