Idea: A brilliant and somewhat reckless Tom Marvolo Riddle who created an experiment that got out of hand is born an Immortal.

There is a little known fact about Immortals. The reason that all of the ones the Watchers knew about throughout history were foundlings was because, practically since time began their parents had been abandoning them. While in the early days of civilization not all families who had the misfortune of producing a pre-Immortal abandoned the child shortly after birth, it became the norm, and eventually it became the law.

The reason this fact was not so well known was because all Immortals had been born to a section of society that had isolated itself completely centuries ago, and before its isolation had been secretive as hell. I'm talking about witches and wizards. Immortality is yet another mutation that occurs amongst the magicals who I am certain are mutations themselves.

Wizardkind had viewed abandoning their pre-Immortal children as a kindness, an act of mercy. Virtually all Immortals are incapable of performing magic and were incapable of having children of their own. What do you do with a child that will not only be unable to perform magic like his or her other relatives, is quite likely to outlive several generations of the family, and could never have children of his or her own? Such children would eventually grow to resent their mortal relatives as they had done in the past.

Unlike Squibs, pre-Immortals could be easily detected before they were born. Mothers who carried pre-Immortals would feel off in a way during their pregnancies. A quick exam by a healer would also spot a soon to be pre-Immortal in under a minute. Thanks to a law passed by the British Ministry of Magic several centuries ago by a Minister who viewed Immortals to be an abomination, St. Mungo's as well as every other magical hospital in the British Isles was not allowed to deliver or treat a pre-Immortal even if the mother of said pre-Immortal would die without a healer's intervention.

How do I know this you ask?

I am a wizard, and I'm also a Watcher for the exceedingly brilliant, rather absentminded and extremely disaster prone Tom Marvolo Riddle aka the moron who unleashed Voldemort upon the world, calling into question a number of things including exactly how unique souls actually were if they could be copied the way Tom had managed to do his.

Due to the fact that Tom had already lost his British accent by the time he was discovered in the 60s after an experiment with LSD went tragically wrong and it was assumed he was American, most of his early life including how he had become an Immortal would have remained unknown if the man hadn't come home looking for something and ended up having to clear his name after Harry Potter recognized him.

Now, in 1999, I am able to chronicle the full story of the Immortal known as Tom Marvolo Riddle.
