In Bloodborne, there are a dozen-or-so new locations. In each, you can light several lanterns, which allow you to respawn in a given location. All of the lanterns, once lit, are available via the tombs in Hunter's Dream and they are used as fast travel landmarks. However, to light a lantern, you need to visit the location first. The above map presents all of the locations that you can visit and where you can light lanterns. To get to some of the locations, you first need to meet certain conditions (e.g. own the Tonsil Stone or Cainhurst Castle Beckoning), while the others become available after you kill certain opponents. Locations of bosses have been marked with a separate icon, just like the presence of hunters (not necessarily hostile ones).
