Regions or "territories" of Black Desert. The name of the territory does NOT necessarily equal the faction ruling it. Guilds can conquer territories or parts of them as part of the game mechanics. NPC-based faction rule is unalterable. For example most of the Balenos territory is under the rule of the Republic of Calpheon currently as is the territory of Serendia, regardless of which guild controls the whole territory or the majority of its nodes.
