Hi I have made another one of my fan creations here https://www.drivethrurpg.com/m/product/358952
Where I have reimagined the history in essence the divide doesn't go up immediately, there are three new elven races with Diamond, Sapphire and Emerald hearts, a settler/pioneer profession, and rules for ideological and stronghold social(political combat), and 6 new monsters themed around indigenous American mythos.
I intend to improve upon it with the creation of an undivided map(an old clan of desert dwarves Inhabit that area, with some silicate peaks) as soon as possible too
