Illyana looked up, startled, at the greeting. She hadn't been expecting to find anyone else in this section of the library. She took in the man's appearance and extended her senses. He didn't read as evil, but he had a strong presence of magic about him, which both put Illyana more at ease and raised her guard. Perhaps he'd be able to help her.
"Hello," she said, offering a smile of her own. "Yes, I have." She offered the older gentleman her hand. "Illyana Rasputin. I just arrived here two days ago." Clark had said he'd been on the Planet for something like a week. She wondered how long this man had been here. If he'd been here longer than she had, perhaps he'd have more insight as to how things worked here.
