Einar Fenrir, A Wolf Faunas with strange abilities due to his lineage, was a White Fang member up until two years ago when he had an argument with their leader, Adam Taurus he then left. If their was one regret he had was that he never confessed or even showed his face to 'her'. For a while after that he had been on the run. Until he was found by a woman, Raven Branwen. She took her in to her tribe and treated him as if he was her son for a short year. Then she asked him- more like forced him to go to Beacon academy where hopefully the broken boy might get fixed and where finally he might unlock his semblance. By his side is Gungnir, his Spear with mystical carvings all the way down the blade and pole which increased its deadliness as well as his twin short swords, Hel and Heim each having similar carvings to Gungnir but instead of more deadliness it gives one power over ice the other fire, Hel and Heim can both be turned into pistols which shoot bullets made out of their respective element. (Gungnir looks like a black poled, white bladed version of Gae Bolg From Fate Zero: https://thumbs.gfycat.com/InnocentDearFennecfox-mobile.jpg . Hel and Heim look like Kanshou And Byakuya from also Fate Zero but one having a fully ice blue blade the other a fire red blade: https://plamoya.com/bmz_cache/d/d2db792140bbd5050e55ddab85144bc4.image.500x247.jpg . Their Pistol Forms Look like two Trident-Silver Horn's From The Irregular At Magic Highschool but one in Ice blue again and again the other in fire red: https://cdnb.artstation.com/p/assets/images/images/003/044/899/large/casper-talvio-final3small.jpg?1468936912 .)
The Powers he gets from his lineage are simple, slight domain over fire and ice which is greatly enhanced with Hel and Heim in his hands. The Other Power are silver chains which can bind his enemy which come out of his back (They look like Adamantite chains from naruto but in Silver. The Myth the power is inspired from are the chains which bind Fenrir in Norse Myth's)
