Loyalty. It has taken so long for him to learn what his brother and his friend and his teacher had tried to get him to see, to learn what they had known near instinctively. Sasuke wondered why, when Konoha had wronged them so much, why they still gave everything for the village. It took him years and several wars and the soft smile on a dying Naruto's face and the despairing scream in a bloodied Sakura's throat that he couldn't voice himself to get him to see why they had prized loyalty. So when he saw a child in pain, a child who held the same emblem he had emblazoned on the chest of his robes, he stepped forward and cut down the aggressor. With words and not a sword, because this world had no ninja.
"What is a wizard?" he sneered with all the disdain of a noble clan that existed not in this dimension. "Before me is an idiot waving around a magic stick. Is your wand all the wizardry that you are?"
"My family has been magical since the Plantagenet kings still ruled the magical world, you ignorant mudblood."
"Shall we then match your blood with mine? I will even fight with no wand, as befits a 'mudblood'. Or is the fact that you were birthed out of your father's sister's womb all that you can claim for your so-called 'blood purity'?"
The Uchiha clan has always had an affinity with fire. Hogwarts learned that day that it was a mistake to anger, or even irritate, someone who held Fire as part of their soul.
Sagara Sasuke, eleven years old, was from then entrenched in the hierarchy of the school as Dangerous.
Sasuke did not care for labels. He kept to himself and haunted the library, wanting to know more about these people who had the potential to attain the power of the shinobi and did not. He read of histories and inventions and dark lords.
At the end of it, he snorted.
It was fear.
They were afraid of their own power.
Their institutions were built to hide and curtail that power. They weakened themselves to the point that those without magic strengthened and flourished while they rotted from the inside, unable to grow out of their self-imposed boundaries.
A body slid into the bench opposite him. Grey eyes watched him calmly. "I like your eyes," the teenager said. "With those eyes of rebellion, of understanding, will you join the Ravenclaw Research Group?"
It was the first time in two centuries that the RRG had a first year representative.
After all, Uchiha Sasuke had felt the most free when he was part of Taka-han. Eagles were almost the same as hawks and ravens nearly the same as crows.
