Fire is pure, cleansing, and strong. The weak and impure burn, while the strong survive. Fire is useful as a tool, but must be respected. It is dangerous when uncontrolled.
Surt's personality is very much compared to fire, while he can have control over himself and be calm like a candle flame. He can be quickly angered and rage like an inferno, he is a great leader and brilliant battle tactician. He is wise and intelligent for his age yet still has the fierce aggression of a great warrior. He is kind to those he calls friends and will fight for them if they are threatened. He holds honor very highly and will not back down from anything. Surtur believes that fire is pure, cleansing, and strong. The weak and impure burn, while the strong survive. Fire is useful as a tool, but must be respected. It is dangerous when uncontrolled. He teaches this dogma to his people, instructing it as a way to live.
Surtur commonly wears cloth pants showing his bare chest, when he goes to battle he uses his magic over fire to manifest blazingly hot iron and a great iron sword covered in flames. The armor and sword he crafted himself, designed to grow with him and be nearly indestructible.
Surtur has been around for thousands of years, he existed when the world was in its ice age and humans were still hardly evolving from apes. Back then the world was covered with many races of giants and other creatures. He and his species ruled and fought for hundreds of years , not only great warriors but master architects and blacksmiths, in till the world started to change. As other species died out and humans spread through the world, his kind went into hiding in great volcanoes. For years they dwelled in a deep hibernation, awakening only to feast and check on the current status the world was in. When they awakened for the last time humans were leading genocide on supernatural creatures and attacked his peoples home. Knowing they would not survive from all the numbers the humans had, they fled, hearing of a reservation for different species. The Fire Giants, led by their King is journeying their now. Hoping to find a new home for his people, though his race has been reduced to hardly even a hundred giants. He still has hope that he and his people can survive.
