This is castle design similar to Heroes 3 concept. This set contains set of 7 buildings of dwarf army units and 1 for hero tent + 1 main building.This design were used in Game “Land of wonders” available here at google play: https://play.google.com/store/apps/details?id=com.ugiugiugi.test All of them were prepare in purpose of turn base strategy game, but might be lavaraged as well as a part of RPG game.
I reccomend to use it with this set which fit it: http://graphicriver.net/item/dwarf-army-game-sprite-sheet/12236956
