Traitor's Curse.

Intro the Weaver. a name that strikes fear into the hearts of all who hear it. but one name is more terrifying than even the Weaver's. and that name is... Traitor's Curse. a silver unicorn allied to the spirit element, the spirit allied silver unicorn. spirit wielders and silver unicorn riders are mortal enemies because they are evenly matched in power, but now Traitor's Curse has appeared with unmatched power. and the only person he listens to is you. his rider. he hatched for you giving up his immortality to have you as his rider. but these unicorns aren't the sweet ones in the stories. the true unicorns are bloodthirsty monsters, with bad tempers, a longing to fight and the lust for mest, and the only ones they obey are their riders. some unicorns hatch without riders and they live forever as uncontrollable monsters that are nothing but rotting skeletons. spirit wielders are not welcome on the Island of Unicorns after the Weaver, a spirit wielder killed the fallen 24, so when the Island's leader found out that you were a spirit wielder you fled to America with Traitor's Curse knowing you wouldn't be followed. you thought you were safe but Hydra learned about you and started looking for you. you managed to escape and now you and Traitor's Curse are hiding out in the Grand Canyon. but the avengers are now looking for what Hydra is trying to catch and they're getting closer. but they're unaware of the danger they are in. when you are riding or touching Traitor's Curse you can summon his magic and use it. your powers as a spirit wielder are controlling all 5 elements ( water, fire, earth, air and spirit), using a specific element to create a weapon, using the spirit element to make something like an arrow appear in a different spot then where you shot it, and as a spirit wielder when you summon any of the elements you have to summon the spirit element too and that can cause you and Traitor's Curse to become that element.
