There are several characters with whom Link cannot speak. Most of these NPCs are there as part of the background scenery, and most will give a generic response to any conversation attempt. Others, however, have specific functions that cannot be activated without certain items or equipment upgrades. For example, Renado, Luda, Telma, and Ashei can only be talked to after you have Master Sword and have obtained the Broken Picori Blade from the Elemental Sanctuary. Some characters do not speak Hylian, such as Twili Midna or Oocca. Others only talk in foreign tongues, such as Gorons and Zora s.
