With regards to your son's operation...
Well, we've got good news and bad news. — Catalurgic surgeon
Becoming what's known as a
Chimera is one of any would-be
Catalurgyists greatest nightmares; their body becomes no longer their own as the Rendling flesh implanted within them metastasizes and mutates the rest of their body into a terrible monster. The chance is not insignificant, either; 30% of all implants are failures, and 10% of
those result in a Chimera.
However there's actually a
third outcome that is rarely ever spoken of; when the body manages to resist the cancer of Rendling cells
just enough for an "equilibrium" to be reached. The unfortunate patient's body becomes a microscopic battle ground for the rest of their life, leaving no more space for any future injury or sickness at all.
Pre-Surgery
The good news is, he's not dead. — Catalurgic surgeon
In any human's journey to become a
Catalurgyist, one specific surgery must alway occur; the impanting of the
Thymalladus. This organ is of artificial design, taking specific
Rendling parts and combining with mechanical limiters in order to suppress the natural mutative properties of the monstrous biology.
A kidney is removed, the patient's immune system is suppressed, and the Thymalladus is implanted. If the patient is too weak, their immune system too overwhelmed, or the Thymalladus not properly limited, then death or Chimeric mutation occurs.
This is both absolutely horrific and very, very cool! Well done!
Thank you, that's what I love to hear! :D
