My Little Robin:Alternate Worlds are Magic

Aqua Heart and her boyfriend, Pokemaster got married and decided to raise Robin and Pokemaster agreed to teach Robin magic, but the couple never told Robin that he was abandoned and to make sure he never found out, they hid the necklace in a secret compartment that they made and put the necklace in there so he would hopefully not find it, otherwise he would most likely raise questions about it. As the years progressed, Robin became a skilled unicorn in magic and analysis, even though he was only a colt. But what Robin didn't know also, is that he and 3 other 'ponies' were special in the near future.
