“Good. That's enough,” Deme said. “You may sit down.” Marus remained where he was, face now almost the colour of his robes, and a snarl forming on his lips. Ebryn felt the flow of force, gathering in towards Marus, the first lightning flickers forming around his hands. “That's enough — sit down,” Deme said again. This time the words came from her mouth like a lash, raw with power, and Marus rocked backwards as if struck. The force of her casting washed over the room like a dousing of ice water. Marus returned to his seat like a drunken man, tripping over the feet of fellow students, and lurching from side to side. “So, who understands what I did there?” Deme asked, moving around the floor again. “No? I used the deeper craft to control another's casting. Once you can do this, the inner nature of what we do is revealed to you, and you have achieved the beginning of mastery. “Much of what we will explore in these lessons is about improvement of your craft. So we learn what is common to all casting, not methods specific to any of the orders. Do you understand?” Deme stood in the middle of the room, looking around the chamber, at the rows of faces. “So, let us begin with a few simple mind exercises.”
