Just a riddle I thought of....

I traveled back north.

I visited my family home.

I was gifted a steed in a flowery meadow.

I sought out an old master, but half of his old self.

I climbed the tallest mountain and claimed the blessings of my father and mother.

On my brow, in white and blue, I carry my brother with me.

And at my back, the wind of them all, guiding me forward.

I carry a list. A debt to be paid.

Who am I?
