"Yes, of course, sir, I-..." Kuvarakh paused, grimacing slightly at the thought of Eridanus' rolling his eyes over being called 'sir' yet again. He turned back to Eadfrid, "I, for one, have always understood that the transmutive blending of the incinerating, and, perhaps more importantly, 'atmosphere consuming' quality of fire, with the...how should I describe...'energy polarizing' nature of air, could result in lightning." He looked again at Eridanus, "This was actually what I thought you wanted demonstrated when you referred to a 'fire/air mixed element transmutation', but perhaps a show of lightning is best left for the out-of-doors. In the meantime, I DID have a test in mind that may serve."
He stood up, with two sheets of parchment in his hand. He went to the far corner of the room, placed two bricks side-by-side and put the sheets, stacked flush, on the bricks. He turned back to Eafrid. "What I want to see is the ability to divide your focus at the same time as you work both elements simultaneously. I want to see you lift the top sheet a foot or so above the lower one, and hold it suspended, while at the same time, incinerating the paper beneath without igniting the one above. Air and fire, control and aggression, all at once." He gave Eadfrid a pointed look, "And for the added sense of pressure, The top sheet is your application."
He returned to his seat, leaning closely to Eridanus, whispering, "It isn't really, of course, but he doesn't know that."
