What can you say about this?

So I secretly write, and I don't really know what to make of my work and I need your advice, here's a short excerpt of a "book" I'm writing :-

"Father, it's time." muttered Grey to his father which at the moment was gazing sullenly upwards to the constellations that formed up in the sky of the world.
"Give me a second son, we shall depart soon." He replied, sounding sad and unsure of himself. "Assemble are men Grey, I shall be down in a minute, leave me in peace for a while."
"Are you sure?." Grey replied flustered.
"Yes son, assemble our forces and share them some words of encouragement, tell them their purpose..." King Grand replied. " tell them our purpose."
"I shall leave you then father, I will be with men." Grey replied and started off towards the archway exit towards the spiral staircase.
It was a night of anguish, the two kingdoms of the world were about to enter war and the present tumult was just the beginning. Grey was a man now and appointed knight of knights by his King father, ruler of second kingdom, and was given all the power he could muster which almost equaled to father himself. As a young adult he had a desire of reaching such rank, but right now he wasn't really happy about it. He walked down the spiraled stairway descending from Night's Tower where his father currently was, pondering on what's to come after this last night of peace. As he walked down, Grey thought about what was on stake and how life would never be the same again after, win or lose. He thought of what would be lost and gained, thousands of lives would be banished for the sake of power, and that would all come from their side what more on the other?
Grey never liked war, he was different. Though brave and full of valor, he was prudent too. He knew that this war could be prevented, he knew ways for both kingdoms to live in harmony where trades would flourish, both economies would work as great as one, peoples of both shall conform , a life of peace never known to man would exist but no one ever listened. Pride ran in this war, selfishness too. But Grey knew all too well that father was doing this to defend second kingdom not for power but for the kingdom and its people and their freedom, he wanted best for it and he would do everything to grant it. But it was unpreventable, only if King Hargard, ruler of First Kingdom, yielded to King Grand's offer of sharing a more than half a sum of the resources Second Kingdom had to them while they return an equal back, and many other superfluous laws just to entice and reel in the King to a better peaceful world. But what is done is done, he rejected and threatened to destroy the second kingdom to leave it for himself that left Grey and his King Father in loss of words, but kindly enough King Hargard was engrossed with his pride, slipped and shared information on when the attack would come to Second Kingdom.
"You weak fools, First Kingdom shall be the only one in the next fortnight. You, Grand and your vile son shall die by my men's sword, or if you live shall serve under my command." King Hargard shouted
"Close your mouth Hargard, I'll fight back if I have too, but you know war can't change anything, I must keep my people's freedom alive" King Grand replied back, a lot more calm then King Hargard.
"Your freedom, your people's freedom shall be mine nonetheless, everything shall be mine... EVERYTHING! We shall attack by dawn and your kingdom shall fall, no one will survive.." King Hargard spit out and broke away and left the conference hall. Grey watched from behind as the double door was slammed and his father collapsing to the nearest seat, breathing rapidly.
Though this was important information, Grey also knew that it may change, and that made him even wearier, he could have died out of the pressure.


So that's it, I've got a fine plot happening but I just want to know how the writing was, please share your thoughts, I don't mind if it's harsh I just need honest opinions. It would help me a lot, thanks :)
