Forum:Jagers & Sparks?

Unless, at some point in my readings and random clicking both on GG and here, I have an idea that hasn't been mentioned elsewhere. Note that this is purely speculation. I know Jagers were created from the best warriors, hence it being speculation.

Is it possible for a Jager to have the Spark? What if they were a Spark before drinking the Jagerbrau? Would the "Madness" of being a Spark possibly help against the side effects of the Brau? Could Spark abilities develop afterwards? What would happen if a Spark did drink JagerBrau? Would they get any side effects, for better or worse?
