The object of the level is that while everyone is trying to get Belle and Beast to fall in प्यार Xaldin was trying to make it so they don't and Beast would turn into a heartless so that they could control his nobody.
Well when आप go there for the first time, your objective is to save The Beast's friends, get him back to his senses and defeat that evil floating heartless thing. When आप go there the सेकंड time, आप have to help The Beast get back "something he held dear" to his heart, which was the rose he had. Once आप did that आप had to kill Xaldin, the organization member responsible for all the trouble that went on in his castle. I HOPE THAT जवाब THE सवाल <D......
