Loki: Hey Sigyn?
Sigyn: Yeah?
Loki: Your power is nerfing and buffing, right?
Sigyn: Uh, yep. Binding or releasing the potential of one or more targets.
Loki: How does it work exactly?
Sigyn: When I'm trying to bind something, I have to focus on a specific attribute and then I target the source of the attribute. So if I want a person to stop moving, I could target the muscles in their legs, the connections between muscles and brain, or the brain itself. The analogy extends to magic, intellect, mental fortitude etc. and the target need not be a sentient being.
Loki: And unbinding is just the reverse of that.
Sigyn: Pretty much. Just a little push to get something up to optimal capacity. It's a lot harder to work with objects of power or people who are already operating at peak efficiency.
Loki: Because you're essentially pushing against the laws of reality and forcing them to agree with you.
Sigyn: I suppose. What's with the sudden curiousity?
Loki: ...the universe is matter and matter is atoms and atoms are protons and neutrons and electrons. Protons and neutrons are bound together by nuclear force and protons and neutrons themselves are quarks bound together by gluons mediating strong interactions. All matter is bound together by universal forces - bound! Gravitional attraction, chemical bonds, quantum interactions - the power to unbind these fundamental interactions or strengthen them beyond their existing scope...
Taken to the logical extreme you theoretically have the ability to reduce the entire universe to its fundamental particles with a mere thought! Or collapse it into a point the size of a pinhead!
Sigyn: ...yeah you lost me at quarks.
Loki: Huh. Who could have guessed that your terrible grasp of physics is in fact what is keeping us all from total annihilation.
