Remnant
The World of Remnant is shaped by the power of the Prime crystals that travel through the earth like veins. The land around these veins are rich with natural resources and surrounded by forests and rivers.
Castles build around the Prime Crystals become Prime Kingdoms with any Village, town, or city within a suitable distance of the Crystal veins become its territory. Lesser kingdoms are built outside the Vein's reach and are essential vessels of the prosperous Prime Kingdoms with their barren landscapes.
