In my world, magic is a prominant force but its not as common as in most fantasys. First off, all magic is punishable by death. After an event called the Mage War, most of the planet was left in ruins, causing all technology to revert back into the Dark Ages. Mages still exist, some actually survivers of the Mage War, but they are in hiding because the events of the War was so devestating, its effects are still felt after two thousand years.
Also magic weapons aren't really that impressive. They are not given special powers or anything of the like. Most magical weapons are basically regular weapons but slightly stronger than average. There are some weapons that have special abilities, but they are exceptions.
The closest thing in my world that can be an equivelent to other magical weapons are weapons made by the Iminori, a race of semi-divine humans that were nearly wiped out during Mage War, and with them, the art of making their weapons.
The reason why Iminori weapons are so powerful is because they are forged from Sunstone, a glass-like substance that is nearly impossible to forge because they actually absorb heat.
Iminori weapons can in some ways be similar to Valaryian Steel swords from Game of Thrones, but unlike them, there is actually a limited number of them. Where as Game of Thrones has almost 3000 Valaryian Steel weapons, there are barely a hundred Iminori weapons.
Is this a good idea or not?
