Sanctuaries (synonyms: sanctums) are sacred places that offer protection from outside threats. In fantasy worlds these may be areas of peaceful respite where undead and demonic forces cannot enter. In game-oriented worlds they may be locations where players can save their progress, rest, or heal. Sanctuaries may be part of a church or temple, or castle, or may be found in extensive catacombs, crypts & mausoleums, and graveyards.
