Rohan could only smile and laugh, glad his party tricks were still worth the practice he put into them. He let her touch the coin--unable to resist drawing his thumb on the back of her finger. "If I told you how I did it then it wouldn't be a magic trick and you would not be utterly dazzled with my charm." He teased. "Nothing is enchanted. It is not actual magic with songspells and smoke. Just a coin and imagination."
He then went on, shaking his head. "I think I misunderstood your use of the word summon. They sort of just call on them with the horns; at least as far as I know! They would blow into it and you could hear the sound for a few miles. Sooner or later the creature being called comes. Maybe it's like if you were calling your pet from across the yard? But...across the city?" He looked perplexed at the idea, running a hand through his ginger mop before shrugging it off.
