I really liked this! Your warrior character was interesting - the fact that he's repulsed by the water but is also born from it (so I'm guessing he's some kind of water-spirit/being/whatever?), and his father's madness and death. Very interesting indeed... *strokes beard*. He also has a sicknasty weapon.

Your final line was beautiful - it was completely the right way to bring the whole story together and end it.

Some of your word choices, though, seemed a bit off to me. For example:

"...the cadence of his heart trembling in time..." - why not use 'rhythm' here rather than 'cadence'? The uncommon word really jolted me out of the flow of your story. The same goes for "cerulean mane" - why not 'blue'?

I don't know... it's just, to my mind anyway, 'cerulean' doesn't do anything that 'blue' couldn't. Feel free to ignore me, though... obviously. Haha.

Anyway, that was an awesome story. I really love your writing style. :-)
