Kithvari

Kithvari is a maker god, and the patron deity of crafters, metal smiths, carpenters, and masons. There is no being spirit or mortal who has sight like Kithvari. He can peer at an object or material and see everything about it, from it's history to it's potential when used in crafting. Though Mythserela  is credited for envisioning the Ayeshastra temple, it was Kithvari who built it. Through deep focus and skill Kithvari has created some of the greatest weapons and talismans to ever circulate the Ismat Empire. He operates by drawing very purposeful energy into crystals that he imbeds into tools to make them magical.  Through this technique he has made arrows that can turn into vicious animals, swords that can morph into blazing streaks of light, and clothes that can shift their appearance. In the current age, and by a magical law that Kithvari opted to bound himself too, all of his creations can only be used once. - the arrows will turn into an animal to attack a foe and them almost immediately disintegrate, and a blazing sword is good for one battle. This is in place to prevent Kithvari's weapons from destroying the world. In an earlier age, Kithvari even destroyed all his old creations when he saw how they were being used. There are however four creations that he did not destroy, but no one knows anything about them, and even Kithvari has taken steps to distance his memory of them. 
There is an exception to his law of single use. During a festival that takes place every four years during an eclipse, when the light exhibits powerful properties on its own, Kithvari can turn this light into an ismat steel creation. Although these items are not as devastatingly powerful as some of Kithvari's earlier creations, these are not single use items. Furthermore, through ritualized spell, the magic of these items are inspired by the hero that they are given to, making it a perfect tool for their endeavors that fits with their personality and spirit.
