The being before him was alive but they were missing half their body. To put it in terms a human would understand, their left side was still there but the right side was just gone. He saw a dantian safely tucked in some flesh of metal and stone.
They had 4 limbs left intact but they were not fixed hands and feet but amorphous crystals that shaped to their needs. The head, such as it was, had been spared just barely but still lost a good shave of it!
Unlike the people he treated for most of his life, there was no brain but an interlaced crystal and metal lattice suspended in a kind of liquid inside them. He saw it was not a delicate thing like a mortal's would be but extremely resilient.
The liquid was obviously a weak point but the skull had deflected whatever struck the rest of the body so it was clear that only the ligaments were the weak point to cause the damage he saw.
