The Crypta (秘匿の聖室（クリュプタ） Hitoku no Seishitsu (Kuryuputa) , "Sacred Room of Concealment") is an Unrestricted Spell that is used to conceal the presence of the Star of Darkness Castle, and the Palace of Heaven's Road to the outside world. A dark starry sky will always be shown inside the Star of Darkness Castle, while in the Palace of Heaven's Road's case, a brightly shining sun is always shown.
