When Jo used the extinguisher, Cyrus felt the slight waver in his magic's foothold but he just put forth more to maintain it. A second later he found out what the cause was. A weird white substance that seemed to stick all over the ground and release a pungent odor. Then her words came in. A breif scrawl holding none of their previous girlishness, rather just a vague sense of fear. He chuckled and made the flame turn into a serpent that bared it's fangs at the girl before he called it back. Rather then going through the book, Cyrus' magic simply disappeared from Jo's world. With a smile he began to write.
"*That was magic. My magic. Nothing more, Nothing less. *" He did slow, deliberate lines, enjoying the feeling of being right. He dipped his quill back in the inkwell and tapped on the edge of the page for a second before continuing. "* I have a hypothesis. This book is merely a gateway. For our words and our actions. It is what allowed me to use my magic where ever you are..and for you to spray....whatever this foul smelling viscous liquid/solid is, into my world. I have never been one on the occult but...*" He scooped up some dirt and grass from his new spot away from the extinguisher fluids and put it into the book. Like he thought it disappeared, forming on the other side. Cyrus began writing again just below where he put the dirt to make his point. "* This is the land that we live on. Do not call me a child, or stupid, or even this 'roleplayer'. I am a magus. I use magic. And I LIVE IN EINHAL.*" He capitalized the last bit and underlined it to show his obvious frustration, and rather then using magic again, he settled for writing aggressively.
"* I know not who you are, where you live, or even where this book of your's came from. All I know is what I have observed. *" He drew a line to signify he was done before putting the book into the folds of his cloak and looking at the white mass that was sprayed across the ground.
