I would suggest a couple of things that really need addressing.
Firstly, you have a tendency to let your sentences ramble on a bit too long e.g.:
"A clean shaven man, of impeccable personal hygeine, dark brown hair normally graced his broad shoulders but now a topknotted ponytail jutted from his close fitting but well protecting helmet, he wore a full suit of sturdy but flexible mail encased in heavy spiked plate made of rare black steel, near impenetrable, his immense warhammer ended many a man in the grip of such a mighty warrior, though such a fearsome man was a most worthy opponent for any warrior he was not invincible."
and
"Gangrenar was its name, a bountiful land, once part of the union, once free from the holds and constraints of money, once happy, now ruled by despots who wished everyone decent, with decent values, a sense of community and a sense of right and wrong suppressed, men whose arrogance made them brake off from the union and whose bitterness made them wage war with those who had nurtured gangrenar into the thriving metropolis it now is, other countries declared sovereignty, saying that they did not want a part in the war and condemning themselves to a life of hardship and destitiution away from the caring embrace of the union, most countrys knew this but were more afraid of gangrenar than of national ruin. the once proud union of ten was now an alliance of three."
I don't think there's any argument about that point. Start chopping
The other thing is that you repeat the same concepts in different ways where the single well-turned phrase ought to be enough e.g.:
"...his immense warhammer ended many a man in the grip of such a mighty warrior, though such a fearsome man was a most worthy opponent for any warrior he was not invincible"
Might I suggest instead?
"His immense warhammer, wielded with a seasoned warrior's expertise, ended many a mighty foe though Troden, fearsome as he was and contrary to rumour, was not invincible."
Sorry, not trying to rewrite it for you, or saying that I've come up with a well-turned phrase myself, but you need to get a lot tougher on yourself.
That said, you definitely have a feel for this kind of writing, and you explain the situation well. Take on board Scalem X's comment, it's valid.
I know you said don't mention punctuation and capital's, but don't you think that since so many people mention it, you should deal with it? Clean it up! and don't be downhearted - I liked it. You can definitely do this.
