As the title says, I'm very concerned about accidental plagiarism. I would like to state up-front that I am heavily inspired by Stephen King's "The Dark Tower" series so as to be completely transparent. I love the series, and am fascinated by how King popularized a possible new sub-genre of fantasy, the fantasy western. I want to contribute my own work to this fairly new sub-genre, but as I step back and look closely, I'm beginning to wonder if I should just scrap it altogether and start something brand new. I would like to ask for guidance after I explain my idea, and would absolutely appreciate any advice.
My book series takes place on a planet entirely different from ours that is still recovering from a Biblical apocalypse. It has been discovered that the Devil is part of a larger group of corrupted entities (Lovecraftian in nature) called the Eldritch, and any malevolent supernatural creature falls under this classification as a "lesser" Eldritch. In response to a period of time called the Judgement Days in which Christ came and smiled the Antichrist, a faction called the Holy Dominion of God rose up and is still attempting to wrestle the lawless frontier. However, a loose collection of massive cities exists outside the control/influence of both the Dominion and their agents, and these cities make up the Circle. The Circle has a culture much more akin to that of the 1920s-1940s, down to the dress style, weapons, black-and-white television, radio, music, organized crime, etc. The Circle's cities are also home to powerful corporations.
The two main special agents of the Dominion are the Inquisitors and the Rangers. The main character is an Ranger/excommunicated Ranger (still haven't worked out that one yet), and I plan to do a couple short stories that lead into the main series and follow the Ranger's adventures.
So, I would like to hear what you think. I think this is way too derivative, but I don't know how to fix it in a way that would satisfy me. The comparisons to the Dark Tower will be inevitable, and while the main character does take inspiration from Roland Deschain, he mainly takes inspiration from the character that inspired Roland, Clint Eastwood's Man with No Name. The mysterious stranger who solves problems with his revolver rather than through diplomacy, rolling into town and hardly uttering a word.
Should I scrap it? Should I scrap most of it and try and start from there? If so, does anybody have any tips that could point me in the right direction?
