I do not in any way vouch for the quality or ultimate outcome of this indie-written title, but it's currently temporarily free in the Amazon Kindle store:
The Dark Lord's Handbook by Paul Dale
To become a Dark Lord is no easy thing. The simple ambition to hold dominion over the world and bend all to your will sounds straightforward but it's not. There's armies to raise, fortresses to build, heroes to defeat, battles to be fought, hours of endless soliloquy in front of the mirror – it's a never ending job. Not to mention deciding what to wear. (After hours, days, even weeks of consideration, it will be black, so save yourself some time.)
After many spectacular failures, Evil decided to lend more than inspiration to these would be tyrants. He wrote an easy to follow Dark Lord's Handbook. And yet the next Dark Lord that came along screwed up like all the others. What good was a Handbook if they didn't RTFM?
It had been hundreds of years, and the Handbook had been lost in the annals of time, along with all that was mythic and exciting in the world, until one day a randy dragon had a chance encounter. Nine months later a Dark Lord was born (for even a Dark Lord has a mother).
It took a while but the orc who had been looking after the Handbook all this time delivered it to this new contender, Morden.
To become a Dark Lord is no easy thing. Morden had better be a quick study.
