How do you feel about a mage and his familiar in an alternate universe where mages and humans live in an uneasy truce with one another? (I was thinking urban fantasy [i]a la[/i] [i]The Order: 1886[/i] but with a lot more magic.)

Possibly, some kind of Mage Council rivals the human government in terms of power and amidst growing unrest between both factions, a series of massacres take place within the massive city, leading both parties to blame each other despite the dead consisting of both mages and humans.

Something along those lines. Let me know if you're interested!
