The races of Kuramen are a strange lot, descending down a long lineage from the First Race; prone to dramatic evolutions and born to a world divided, each does the best it can to survive.
Magic is like alcohol, the more that is used, the more it causes a hangover later on and the less judgement one has when using it. If one waits a while after casting a spell, things "detoxify." A cantrip or two is like a sip of weak beer, whilst a large creation spell is like a bottle of vodka. Cast something too big and you can die from magic intoxication.
