I make the three sisters cast a spell to bless the throne with their powers, and also the powers of the Hollow, the nexus and the Seer (?) So now we've got a bigger reason to fight for it
I go away with the throne to make sure you won't take it so easy, then I just use cloaking, which means you'll never know where I am or where the throne is, also making me and the throen invisible. This can be reverted by stripping my cloaking power... Oh damn, I revealed it ><
That's just another time loop, so I break it and become of my age again. Then I kick you out of the throne and you go flying to the North Pole, then I shield myself, get to the north pole, and when I see you freezed, it blow you up.
I make you sign a contract, and you end up in an alternate timeline, where you've never born. 24 hours later you dissapear/cease to exist, and the Throne recreates in the real world.
You're going a long way for some wood. Before I disappeared, I reversed myself to before I signed a contract (why would I even do that?) and rip the contract. And then I take the throne.
My powers are innate, so you can't take them. I reverse myself to the first time I took the throne and not take it. Therefor, I have never taken the throne.
I see you teleporting, and then I go to the same parallel universe. Then I make you meet your parallel self and you both explode.
Then I just ask a wizard friend to make a portal, and I go back to the real universe.
