Alara

You have been bound by a spell of incredible power. it is a world binding, to break the spell the world would need to be drained of life or utterly destroyed. youbare bound to her will. her commands are paramount and unresistable. the only caveat is the wording must be precise, and you must posses the ability. (if you can't fly then her commanding it won't make it happen) Be what ever you want, decide how you got into this situation. A summoning for example. Have fun.
