Dungeons and Dragons is a great game and a terrific innovation on war games, but it has a dark side. First there was that
Tom Hanks movie. Then the game spawned a whole category of fiction that is no less than a crime against humanity.
The problem with D&D-inspired fiction isn't especially with the semi-medieval setting, the funny-ha-ha uncouth barbarians, or the haughty elves. The problem is that most of the stories in the "based on a D&D campaign!" genre can be summed up like this: "Some guys fought some guys, then they went for ale." A gripping game is not a gripping read.
So the first thing you may think when you hear that
The Gods of Arr-Kelaan is based on a D&D game is that you're in for a lot of pain. You're not.
