Riddles in the Downs

[Huinesoron]

I am Gold.
I take what I want, looking ever higher:
From the centre
To the east
Even to the west.
In the end I claim my desire, and am forgotten.
I am Gold.

I am Bejewelled.
I stride the decks, secure in my pride.
I claim blood
For my blood;
In blood I fall.
In the end my heirs are lesser and greater than I.
I am Bejewelled.

I am Wolf.
I claim a hand; I claim a throne.
I am denied,
I return,
I rule the winter long.
In the end I fall, avenging son slain by avenging son.
I am Wolf.

You may find multiple characters along the way, but the answer to the riddle is one word that links the three verses together.
