It’s all muscle memory. Reflexes that normally die in time, but stick to the Wight King.
Though it’s not food that sates his hunger.
Not in the same way as humans. Water will quickly evaporate in his body and be released by breathing. Food is entirely consumed by his body in order to pull a meagre amount of energy out of it, the Wight King can’t live on this, but his body does consume any kind of biological elements animal or vegetal, even bones would be consumed.
I guess whether they are genuine or fake, is only a matter of perspective.
Are they necessary? No. Are they meaningful? Maybe. :3
With training and concentration he can completely shut down all living funcionts of his body and restart them later, as long as he has energy he’s alive, everything else is not necessary, just reflexes.
The blood in his veins is not human blood anymore, it’s very similar but its effects and use in the body is different. It’s not really living, but it’s not dead either. The Wight King’s ashen skin isn’t really related to the blood.
The Wight King wouldn’t be able to reproduce in the same way than humans. I still have to think about how things would go, but… spawn, is a well-chosen word.
