Istredd is glad to hear him say he wants to try it now. It is easier to convince yourself to stop when not involved, but he did want to give him a chance. His smile is genuine and he nods.

"That's a good place to start. Follow me."

Istredd leads Wilhelm up one of the floors and through a section of books, so his mind can create one of those places that would be a reading nook for anyone else. For them though they step into this sudden open space that appears to be a wide open room with walls and everything made of stone. This is all very specifically chosen because it will be the safest if Wilhelm loses control of the fire. He wouldn't have to worry about books or the nice library feel of the front room.

It actually resembles very closely a room that he and his fellow mages were in as they began to train, so he's creating it from memory. Despite it being made all of stone it is light in there, all a formation of his mind. Istredd waits for Wilhelm to come in and get adjusted, it's a simple room after all.

"Ready?"

Istredd nods to him and then easily calls fire to him. His hands burst into flame but still seem very well contained to his palms, curling into small fireballs hovering there. A good easy place to start.

"As a mage, we channel magic, it's true energy, the life force of the world all around you. Energy can't be destroyed but it can be changed. What you're trying to do is tap into that energy and let it flow through you, don't see it as an exterior force."

He tossed the fireball up into the air as one might lob a softball.

"You can't hurt anything in here. Try to catch it and hold it in your hand."
