Erandur frowned deeply when the young lady's first reaction to what he was doing was fear. Was she so sheltered, so wound up in her own ways that she couldn't see anything outside of it?
All he did was cast what she was trying to learn, and cast a spell to create an illusion on top of it.
The 'dragon' never vanished, though. Its ethereal being remained on their plane, right there. In middle of the lobby of the hotel. Erandur reached forward and touched its snout. He was too old to care about almost any one thought of him. "Ben has, I guess. I gave him a Soul Gem containing such things, as a way to be entertained. Though, neither of them were the same as this one, though." Not that it mattered, it was still an illusion.
"This is simply an illusion, mixed with some DragonTongue." Giving the 'dragon' a gentle tap, it dissipated in to nothing. "Do you not know nothing about them? What exactly have you been taught?"
His eyes glanced to the book, then to Katherine. He knew she couldn't trust him at the moment, even if he was still recovering from doing what no one else seemed to have the brashness to do.
"Whomever has been teaching you, has been far too lacking in their ways." His blue eyes knowingly went to the shadow that cast itself in the hallway. A "Guardian Angel?" Erandur hoped for one of his own, but none were needed in this situation.
