Speak to Strahad Farsan in Ratchet to learn the ability to summon a Felsteed.
I would give you a reward for your patience and hard work. But know this, the ability to summon a Felsteed will be much more difficult in the future. You will have to earn it... and it will not be easy.
For now, go with the power to summon such a creature and use it as you see fit.
