Okay, here's the challenge.
After his defeat at the hands of the Dovakin, Alduin fled to another world. When he got there he met strange dragon, found new magic, and many new creatures. After spending a few centuries in this new world, Alduin noticed that the strange dragons were taking in human children and training them. Not to be out done, Alduin takes in a human child and trains him to be the best. When the child reached the age of eleven, Alduin decided it was time for his 'child' to prove himself, and sent him off into the world. Although he already knows much of the Thu'um, his body is not strong enough to handle the toll it takes.
So he uses his 'magic' sparcly, and defeats all but the strongest of enemies in melee combat, weather it be with sword, dagger staff, or his bare hands. He was trained by aluin, a Nord patron himself, to revel in combat and to never give up and always win, there is no other option. And he will accept none, he represents both his 'father' and the fighting spirit of the Nords,
and he knows the pride of both. His he has black shaggy hair and green eyes, he wears black pants,boots, and shirt. This is until the age of 14, where he starts to wear the nordric armour his father had given him years before, he was not strong enough until this age to fight full in it. He also wears an amulet of Akatosh, as this is both is 'grandfather' and patron God. He is not unbeatable, he has been defeated many times, but each time he is not killed he will train to defeat, if not kill, the one who beat him. He is very proud, especially of his heritage. Insulting his father is a quick way to Hell in his book. After leaving his father, he wandered around eventually becoming a mercenary known to go to any lengths for a cause he deemd worthy. Durring this time he got many offers from mage guilds, but he viewed these mages as weak, and felt nothing but disgust for them. Until the day he met a mage on a mission, in which they had conflicting goals. They both fought, and he lost, at his refusal to admit defeat, and his enemies refusal to kill him, they came to a long struggle. eventually, he could fight no more, and asked his enemy his name. His enemy declared himself Gildarts of Fairy Tail, and left to complete the mission. After this defeat, and in search of the person who had crushed both his body ad pride, went to Fairy Tail, only to find that the person had left on the 100 year mission not 3 days before. Macarov, seeing his potential, asked if he wanted to join Fairy Tail. [name] agreed on the condition that the Guild master fight him and prove his strength. Macarov agreed, and they went to a secluded place to battle. After losing [name] swore service Macarov, and by extension Fairy Tail, until the moment he could beat him in battle. After being in the guild for one year, he had a fearsome reputation for both his loyalty towards his guild, and his ruthlesness against his enemies. He quickly made S-class mage. As a reference he is 3 years older than Erza and Mirajane. What magic he uses is wildly regarded as mysterious, as those who do know keep it to themselves.
I hope this gives someone enough material to work with, this doesn't have to be followed, this is just to give you some ideas . Although I would like to emphasis on NO GOD-LIKE charcter! Seeya!
