Blood Mage
A decent story could do without the politics though. This world has been overrun by monsters and humanity had to adapt etc.. why do countries still use their own currency? You have the (Heros) fighting the monsters and foreign (Heros) etc and they get gold coins from drops but yet they have to use their countries currency to buy houses food etc. You have based this story world as a combination of a semi fantasy world introducing guilds, classes, monsters etc and real world government, world wars, différent countries etc. gold would be the currency to make things simpler.
