A Warrior's Oath

What can I say, I'm a sucker for these kind of tales. The son of a warrior tries to keep his promise to his father, only to find out that there's much more relying on him. He finds himself embarking on an adventure, making new comrades, perfecting his skills and ultimately exceeding what his father expected of him. I plan on making this an epic fantasy, and though the concept might be a little cliche, I'm trying to make my own spin on it.
