My char is a powerful wizard easily able to control all non-magic creatures with ease. However, she must hunt down the two Elvin sisters. One controls powerful Druid magic of her own but does not know how to control it. Often she has knocked herself silly trying to complete some task or another and at other times she can do the most amazing things if she controls the magic correctly. The other sister has taken her on a journey to find some talismans and a book of magic which would both help in teaching her to control her magic and make it stronger. Both sisters realize they must do this before the wizard finds them or their land and it's people could be given over to the cruel leadership of the wizard which would eventually enslave them all.
During this journey the wizard creates mutants to capture them. What ends up happening is one of the two sisters is captured and taken away (you can decide which one) while the other one knocked unconscious in the battle with the mutants but is never found by the mutants that did the damage. When she wakes up she must follow clues left behind and follow them until it takes her to the wizards compound.
Since the wizard needs both sisters he lures the other sister once she regains consciousness to her sisters whereabouts leading the sister who is being led there to believe that she is following trails on her own, using her magic or her tracking skills and not being lured there.
In the end only one sister is thought to survive. The other must not let her wrath force her into making a rash mistake which leads to her capture.
However, a cat makes it's appearance and is advising both sides on what to do. It is giving advise to the one sister on how to kill the wizard and at the same time it is telling the wizard where the other sister is at all times.
No one knows on either side what it is the cat's real intentions are. The cat is obviously a creature of magic but is not the making of either side.
In the end eventually we find out the goals of this creature and it could be the end of both the wizard and the one remaining sister, or it could favor the sister or the wizard.
If the sister defeats the wizard she may bring her sister back to life but this too would have an unknown cost. If the wizard wins he may keep the one sister alive as a personal slave now that the wizard has all the magic controlled and can rule the land and it's people unchallenged.
All is up for discussion.
