Fate.
By definition, fate was the development of events beyond an individual's control, development determined by a supernatural or higher power.
However, in a world of mana and universal law, the definition of fate couldn't be so simple.
If Karma was the web that connected all things, then Fate was a representation of the possible futures that could sprout from those connections.
The "fate" that one usually thought of when the term was mentioned, one's ultimate fate that determined the course of their life, was a representation of the karma between oneself and the universe itself.
Yet, even this definition was only on the surface level. Anyone who had some sort of comprehensive ability could draw these connections, but that didn't mean they could suddenly wield fate.
No, for someone blessed with such a power, the understanding required was far more intrinsic.
But the problem also stemmed from this fact.
