How are Ruby and Soren's powers outlined, anyway? I don't see limits of what they entail.

Harmonic chaos speeds up gradual change, with a level of randomness to it, kind of like the mutation idea Nix mentioned. Harmonic order extrapolates and/or applies patterns from and to objects. Ruby can easily find patterns and can cause processes to follow patterns which generally make sense (there can be a bit of a chaotic tinge depending on how complex the pattern is, but that takes more thinking).

EDIT: Oh, and Soren can also manipulate probability, as you know. Or, not exactly manipulating probability, but I already explained it to you and it's too complex for me to lay down in words right now.
