Feudal

Power structure built on strict hierarchical land obligations, martial oaths, and blood feuds, driving constant themes of localized loyalty and sudden betrayal.

The thrill of shifting allegiances and the weight of sworn oaths. The constant tension between the security of belonging to a lord's household and the danger of betrayal from within or without.
