Attack

Loki obviously noticed that the two people were staring at him, but he wasn't bothered. If he were in the same position as them he would also doubt the unknown newcomer. 

'Well they can speculate whatever they want, I'll just start scanning these books get a little bit of info then pick the best one.'

Loki went to one of the bookshelves and started to scan the first book he saw. He did a quick scan of the book and flipped through the pages what he saw made him frown. 

'The contents of this book are incomplete, it's only an introduction to what the skill was about. Are all the books like this?' 

Loki started flipping through the other books one by one and all of them were the same only the introduction of the skill was there.
