With a sigh, Heinrich shrugged as chaos ensued around him. "Very well, then I will not hold myself back. Though actually, I'll at least try to simply pacify you. Terribly sorry to get in the way, but as you say... I have a job to do."

 Lazily holding out his hand, it suddenly appeared to be glowing a bright white light, with an odd dark center, almost like a tiny eclipsed sun. The neighboring mercs might have noticed their gunpowder sacks/horns somewhat lighter than before. Heinrich lowered his arm, and began walking toward Grafl, glowing hand clenched in a fist. "Oh my, dear chap, sorry to say that won't work at all. But worry not..." Closing in now, he raised his arm and through the punch, very sudden and quick, a blur of dark light streaking toward poor Grafl now. 

"I always return what I've borrowed, I am a gentleman, after all" He said, punch aimed for Grafl's head flying at inhuman speeds.
