Elian looked down into the abyss of the valley. In pure mathematics, the Nabla is an operator of change. When placed before a scalar field, it reveals the gradient—the direction of the steepest ascent, the arrow of maximum growth. But Elian knew the dark secret of the universe's sign convention.

To the students at the Great Academy, it was simply the Nabla. They used it to calculate the flow of heat through iron, the pull of gravity between cold moons, and the swell of ocean tides. It was a tool of measurement, a tidy operator in their leather-bound textbooks. But Elian knew the dark secret of the
But to Master Elian, it was the "Del"—the symbol of the Descent.
