There was nothing that Aurora hated more than a jealousy person and the one who thinks was above laws and traditions. A greedy friend to Aurora equaled a snake with a very strong poison and at any moment she was vulnerable the snake would attack and take her down once and for all.
Toro started off as a good friend, but then he grew jealous and wanted more. It was clear that he wanted a dragon for himself.
Aurora told him straight and plainly "The dragons belong to me and only me, not just these five... but even the ones who will hatch later on. I control them and I say who they should be claimed by, if you don't believe me Toro you are welcome to try and claim one without my permission" she said softly but her voice was demanding at the same time, and her Low Moor was perfect.
"I'm a true Morrow Your Grace. The dragons will recognize me just by my smell"
