trapped in a bottle

Long ago, Powerful mages walked the earth. These mages lived happily alongside humans, helping out however they could.
However, humans became greedy and tried to capture the mages, the mages who were captured, were sealed in bottles....Like Genies
Cursed to be in there until the bottles open, the mages slowly lost their love for humans...and their former love for the race, became hate
Yes they can gran your wishes, but they may throw a little...twist
