[@Iatos] My OC is a unicorn inventor who wields an element from the other side of the world. Would he be able to keep the element?

For a little backstory on the element, there were 2 big tribes in a great war, they both got low in numbers, both groups were granted a set of elements to aid in their victory. My character, Rockin' Strings, wields the Element of Sound, one of the Elements of Life. When alone, as he would be for this RP as his friends aren't leaving their home again, ass he can do with the element is knock somepony back with a "ray" of sound waves that aren't even half the strength of S3 Twilight's magic rays.
