Arianna rubbed her nose for a moment, thinking " Thestrals are very unique fantastic animals aren't they? They're extremely intelligent and can only been seen by those who have seen death. That might contribute to the wand's unique powers right? " she wasn't very sure that made sense, it was hard to explain why something was so powerful " and elder wood is quite unique too I think, if I remember correctly, in some regions it's believed to have spirits inside too" she nibbled on her nails " other than that, it's quite rare that a wand lasts for so long, with time wand's cores are supposed to slowly fade right? This one never does, I think it's kept alive by it's owner life and strength and I read somewhere that it's supposed to turn into a normal wand just as soon as it's owner dies of a natural death without ever being defeated." she said, ending her speech with curious eyes.
