Emily looked around, `well i know that, well at least my mum said, that my wand core is unicorn hair because i`m unique. And she says hers is veela because she is alluring, but she never mentioned pheonix feather to me. Pheonixes are brave aren`t they? They also have healing powers in their tears so judging by the characteristics of the animal itself i would say it is to help you to be brave and be able to protect yourself from harm" Emily said.
