The Lordship Lands, a campaign world for D&D 5th Edition

The Lordship Lands, so called because the western human nations include more than a dozen petty baronies and counties without a kingdom to be found among them, are split quite literally between a land of might and one of magic. Taking inspiration from works by Neil Gaiman, George R.R. Martin and Sarah J. Maas -- not to mention the old fairy tales that inspired these authors -- the Lordship Lands is split down the middle by a great wall, divided into a land of mortals and a land of faerie. 

To the west is a land of political intrigue and knights in shining armor, where open warfare between one barony or another is always in the air, as petty nobles strive to regain the long-lost power of a once-great kingdom that fell apart centuries ago after the last king died without heirs. Some of these nobles are goodly leaders with their peoples' best interests at heart. Most of them ... not so much.

To the east of this land, and splitting the continent roughly in half, is a great mountain range called The Wall. Atop these mountains is a far more literal wall, a great stone bulwark that, legend says, was built by a race of giants -- a legend given credence by other massive, cyclopean ruins that occasionally dot the landscape, speaking of a time long ago when something -- something very large -- ruled this place.

And beyond The Wall? The eastern portion of this continent is filled with enchanted forests, faerie creatures, and unbridled magic power. 

Regardless of how dim a lord's dreams may grow as forces conspire against him, he and all his subjects know that they are better off here than in the east, where fey rules are in place, the veil between our realm and the Feywild is as thin as paper, and a man can lose his soul forever simply for saying the wrong thing at the wrong time to the wrong eldritch power.
