'Gods, this stinks!' Inoadar thought bitterly, controlling his gag reflex. He had tried heating the bones to the point that he could take scrapings, without it being ash, but nothing came of that. He tried cracking them open, but the marrow he was looking to gain was dessicated to the point of being nothing more than a stain in the hollow of the bone. Nonetheless, he scraped some out and tried as many processes as he could imagine, again, without success.
He had the nagging sense that he was wasting time with simple structural tissue. He moved on to the organs, again slicing and separating different sections based on function, as well as he knew them. But as the day passed, there was nothing gained but a horrific smell that he wondered if he'd ever get out of the place.
No, he knew this was all pointless. He was being overly methodical this time. His educated guess told him that something that didn't prevent a Nuit from transferring, regardless of its condition, was irrelevant to his research. 'All this muscle and bone and sinew...I'm sure it has nothing to do with anything. It is not the reason a Nuit can or cannot inhabit a body. Same with the organs. They don't even USE them, for the most part.'
He knew a Nuit could not go back to a body they'd moved out of. He also knew that the brain was the only truly vital organ to consider. "Sharine's" husband had told him that a body with a nasty head injury was not an option into which to transfer. Technically, the rest of the body could be maimed, but the brain HAD to be in good condition. 'And then once gone, they can not transfer back...It HAS to be the brain!'
There had been something odd when he'd opened the skull to remove the brain. It hadn't occurred to him before. Normally, there would have been a deluge of blood. It not only provides oxygen, it is under pressure enough to provide a cushion. He'd suffered a concussion or two in his life and he remembered being told that they were caused by the brain actually hitting the inside of the skull, due to some impact.
Yet, when he'd cracked the skull and pried it open, the mess was negligible. But the brain had still been quite snug. It must have swollen. He just needed to see if there was some liquid present, and if it was pooled in various cavities or if the tissue itself was swelled with it.
He may not have gained anything yet, but he had narrowed it down, and that was still progress.
