Hi! I'd love to know more about a Seer of Breath! Power-wise and/or personality-wise!

Well first of all they would likely be able to gain Knowledge from their position as a protagonist, or likely learn about being a Hero. Knowing Freedom would likely work better as a Troll, sort of being in a really tyrannically oppressed society, knowing there’s something beyond that, having ideals and goals about detaching from this unjust society. Also Knowing Wind would indeed let them predict air currents and weather forecast stuff.

Now for the fun bits- Knowing the Plot would probably, inherently let them know they’re inside of some sort of narrative, or at least predict where the Plot is headed towards, no plot twists or surprises for them. And Knowing Motion? I could definitely see them being uncannily good at predicting the movements of their enemies, which would make them excel at Hand to Hand combat merely because they could block and avoid most blows, some kind of foresight.
