Klaus sheathed his sword slowly, keeping a careful watch on Kai. But he seemed to be unconscious. Very good. He took a few steps closer and crouched, examining the odd blood/sand combination for a moment before scooping the boy up easily and flinging him over his shoulder. His weight was nothing to the large man, and before long he'd arrived at his lab.
He'd already developed a makeshift containment jar, on the likely chance that he'd need to do something about Tryggvassen in the near future. It took mere moments to insert Kai into the chest high, viscous green fluid filling the tank. As soon as he was sealed in, Klaus went and started fiddling with the dials, sparks flashing along copper wires as he adjusted the settings.
