Uradalla and the Dragon Lantern

What if the roles were reversed in the story of Aladdin, yet both characters being of royalty? One who had been under a magic sleep for 200-years and the other dealing with a kingdom close to falling apart after 200-years of monster attacks.
The Basin of Four is near the point of collapsing: The Kingdom of Allavon had long since fallen; the Kingdom of Novalla was under a curse of thorns; Dragoonia was overrun by wicked, wild dragons; and the Kingdom of Trucorn was all that was standing. In dire need of aid, Trucorn's king decides to marry off one of his daughters to the savage Storm People in hopes of a brighter future. However, Princess Uradalla has better plans and sets off on an adventure to Dragoonia to find a magic fix to everything. Can she find it in a lantern hanging in a crumbling castle?
