My new grimdark science fiction novel - "The Vanquisher of Kings"

I started writing my new novel a week ago. For now I have 4,300 words, the blurb and cover art are ready too:

A warrior named Erilaz and his companions get exiled from their kingdom after a revolution.

He was used to living like a king's child but now he must survive as a nameless outcast without any future.

Erilaz and his friends hide on a distant planet, where they risk they lives every day.

His past motherland slowly forgets about his deeds and gets engulfed by chaos, starvation and a civil war.

There are only three things that give him hope to carry on: his loyal friends, love for his land and the legend of a mysterious warrior and a clever strategist: The Chromed Emperor.

One day he will be back.

Meanwhile, the king of his planet wants to bring peace and prosperity to his land. A single mistake he made calls into question all his plans and hopes. He always seemed to be noble and brave but after becoming the sovereign, he has become increasingly paranoid.

Every shadow looks for him like an implicit threat and every ally may be his enemy. His concerns are justified; however, there is a much worse danger than a band of local rebels.
