They made a vow, their mother will be found!

The Queen Aleena Chronicles is centered around one thing: Queen Aleena. Dr. Robotnik is out to conquer Mobius, what else is new, and some of his plans include: marrying the Queen, kidnapping the Queen, stealing the Queen's crown jewel, and unbalancing the peace in the valley of Mobius. It's, of course, up to Sonic and his siblings to stop Robotnik while using the power of music to settle all their feuds.
