I generally have really cool concepts for magic systems/ worlds pop into my head every so often. These ideas usually get stuck at the concept stage because no plot ideas accompany them. I thought I'd post one up and see if anyone could help me flesh it out.
The concept is this:
In the world of Obeir, anyone can become a mage - all you have to do is sign away your free will.
In signing a Contract, you become unable to disobey your Master's Commands; if your Master Commands you to something physically impossible, you will use magic to get it done.
Historically, Masters have abused their Contractees for wealth, power, and immortality. Unsurprisingly, very few people are willing to sign Contracts, and Contracts are almost always made between siblings.
The conversion from regular human to ever-more-powerful mage is a gradual thing. Every time a Contractee is Commanded to do something outside their current abilities, those abilities extend - with excruciating pain to the Contractee. If the Command is too far outside the Contractee's abilities, the Contractee dies in agony.
On the very, very rare occasions that a Master dies, the Contractee is free and retains whatever powers they have, but cannot become more powerful.
Aaand... that's it. I have no idea what to do with this world I invented.
