Note that everything I say is purely theoretical or observational, and always based on my own conjecture and/or understanding of what has been said. I don't claim to be representative in any way of TheHangedMan's opinions, ideas or established lore.
From what I understood, a bloodline can also gain the Ouramancer disposition by having a history of interactions with Magical Beings, or having a sufficiently powerful ancestry for the spirits to form a minor guardian deity.
That being said, both situations require plenty of luck, or ludicrous amounts of hard work that won't even pay off for the immediate participants. On that note, due to my planned character backstory (should it be approved), it's quite possible that my character's possible future children, grandchildren, etc. would inherit the ability to perform Ouramancy.

EDIT: The idea of nature abhoring destruction confuses me...
May not be the answer our dear GM would make or have in mind at all. But in a sense, the spirits/energy of nature tend to prefer a "natural order" to things. That meaning: nature is a fickle thing. While natural disasters naturally occur, forcing something as vast, moody and powerful as nature to take an unnatural course through magic is like trying to control fate itself. So, in a more direct definition, the destruction brought about by a natural disaster is just a matter of course, while destruction using forces of nature via manipulation of the Karma that constitutes it is destruction—otherwise, it can also be thought of as the destruction of the natural order.
If we wanted to get truly philosophical, we could start inquiring as to whether or not the actions of humans constitute the "will" of natural order, or if humans are innately unnatural and all actions taken by humans are subject to nature's scrutiny. But,
I'd rather not go there.

Basically, I am thinking about having a character with some interaction with the fay and went off the deep end because of it.
Essentially, that entails a, "Congratulations on stumbling upon the domain of fairies!" award. Fairies are... interesting creatures. If TheHangedMan is influenced by the lore I think he's using for the fae, then they're a particularly strange species that have no sense whatsoever of human values and typically can not be seen by humans. They live in an entirely different world, a sort of parallel dimension that they'll only come out of for their own devices or if someone of particularly strong aptitude in magic (or extraordinarily good/bad luck) contacts them to gain some form of artifact.
More on your topic, getting brain scrambled by the blue and orange morality fae is pretty plausible, whether the character had purposely contacted them or merely stumbled upon them.
