Pain.
Horrendous, soul-tearing, mind-numbing pain.
The moment Faxul plunged that knife into his chest, that was what he had felt.
The feeling of having one's organs destroyed inch by inch by a force that just wanted to turn everything it passed through into a mangled piece of undistinguishable flesh was something that couldn't be described in words.
The worst part was that as an Exalted Human, he had more endurance than the typical individual.
Hence, even though almost all of his vital organs had been destroyed, he had been clinging on to life, all while the pain threatened to destroy his mind.
Wasn't death supposed to be peaceful? Why was his like this?
When his best friend ran up to his body and caught him, Faxul had been able to feel it, but he hadn't been able to respond at all, as his mind was in an extreme state of shock.
