It is the site of "Mission 011: Pale Company". Rumors of ghosts in the cave lead Marche to investigate. He then finds a seam and is teleported to the third shrine, where Adrammelech, the Totema of the bangaa, resides. Marche defeats the Totema and the third Crystal shatters. Nargai Cave is also the site of "Mission #058: Royal Ruins", "Mission #078: Water Sigil", and is the spawn location of "Mission #110: Revenge". It can be freed in "Mission #249: Nargai Cave" after "Mission #013: The Bounty".
