The four remains

Long ago there was a desperate man who longed to be king, he wanted to overthrow the king of Rafen, a beautiful kingdom filled with wealth and pride. The only way he could ever get the throne is by magic, something humans like him could never have. In search, he found another world through a portal and entered it, finding himself to stumble upon one of the most powerful creations ever made.
A crystal that controls time, space, and worlds. Crystals that hold immense powers that could even destroy the guardians born with magic. A crystal created by four wizards, A crystal which in such hands will make them invisible. He reached up to grab all of them but they broke into shards scattering across worlds. He only caught one, but that alone is enough power for him. He over-throwed a powerful king who brought his kingdom to a golden age, made the people his slaves, and made his guards search the corners of the world to find the other crystals. Somehow a little girl ended up stumbling across one of these crystals becoming the kingdom's hope.

Would she succeed?
