"Anything that bestowed other-worldly control did not simply attach to human beings with no adverse effects. Humans were not made to do these things. Ros did not need any semblance of a science degree to see the gravity and danger of the situation."

Whoa okay so Adrianes last post got me thinking. 

Laws of physics. Action and reaction. What goes up must come down, etc. what the Zauber team found seems to violate the laws of physics, but what if it doesn't? What if it obeys the fundamental law of conservation of energy? 

In other words, they have magical abilities- the ability to channel one firm of energy into another- but it must come at a trade off. Where are they siphoning that energy from? 

What if every time they used magic, they shortened their life span? For example, after a large outburst of magic, Klaus might find some gray hairs. 

You can see his that'd be terrifying in the hands of the nazis- they'd be complete fine with producing an army of magically enhanced soldiers with very short life spans...

Thoughts?
