Imgig Zu Imgig Zu was an extraplanar monster and the ruler of his people . History . The Song of Selûne . Imgig Zu ' s history was a matter of legend , set down in the Song of Selûne . It began when the wayward young goddess Selûne traveled to another plane and was smitten by a mysterious and attractive warrior , a lord of his people . The stranger persuaded her to use her father ' s wand of power to transport him and his followers to Toril , where they planned to settle . However , once they landed , he revealed his true form and intentions — he was the monstrous Imgig Zu and he and his people were intent on conquest and ruin . He seized her father ' s wand of power and intended to kill the deceived goddess . Fortunately , a brave young wizard named Ostus Agrivar who was riding by raced to her rescue . Although the wizard was not powerful enough to defeat the monsters , he was capable of causing enough confusion and chaos that Selûne could escape . The goddess , now freed from her subjugation , used the only thing she had left : her own life force . Draining her life force away , she imprisoned the monsters inside a pocket dimension within a gigantic moonstone , which should contain them for all time . She reduced the gem , now known as " Selûne ' s Eye " , in size and gave it to Ostus for safe keeping . Escape . However , from inside the gem , Imgig Zu somehow managed to observe a shamanic rite in which the elves of Shadowdale extracted a dark spirit from the infant Cybriana , daughter of Ostus Agrivar . Imgig watched as the dark spirit transformed itself into a living being , an evil drow woman who took the name " Kilili " . Imgig forged a magical link with Kilili , which allowed him to escape into the Realms . However , he needed Cybriana and Kilili together to release the rest of his people from " Selûne ' s Eye " . Kilili fell in with Imgig , and together they hatched their scheme . Imgig Zu once forcibly transported the fire elemental Jogaoh from his home plane to the world of Toril . Employing a Lockstone , Imgig then trapped the powerful fire elemental in the form of a weak dwarf , which in turn bound him to Toril , and furthermore used his " staff of withering " to drain the strength from Jogaoh ' s limbs . Nevertheless , Jogaoh was able to escape . Thus , Imgig placed the Lockstone atop Stoner ' s Needle in the Sword Coast lands with a frozen greater basilisk as guardian . The Lockstone also proved the key to Jogaoh ' s release . Its conditions were the passing of two centuries and to be touched by a living creature . Once these were met , it would restore withered or lost limbs to the one who touched it and transform them back to their original form , but also awake the greater basilisk guardian . Jogaoh feared the basilisk too much to make the climb up and take the Lockstone . The Great Awakening . In the Year of the Dragon , 1352 DR , riding a wyvern , Imgig Zu broke through the wall and magical defenses of Ostus ' s Hold and attacked the aged Ostus Agrivar and his son Priam . Imgig crippled Priam with the " staff of withering " and slew Ostus with a death spell . Then he seized the " Selûne ' s Eye " and left , mocking Priam for his crippled state and inability to threaten him . However , some six years later , Imgig Zu was yet unable to use the " Eye " . By this time , he and Kilili had joined forces with a yuan - ti , gargoyle s , ogre s , and a number of chasme minions . In one day in the Year of the Prince , 1357 DR , Imgig Zu erected a magical tower a day ' s ride north of Waterdeep , and had his yuan - ti and chasme minions find and kidnap female elven magic - user s as he sought out Cybriana . Imgig Zu had determined that it was Kilili ' s own " sister " , Cybriana , whose very presence could make " Selûne ' s Eye " glow like the moon . Kilili had her sport with those that were brought back , testing their power in magical combat and dispatching them with ease until she found her counterpart . The chasme brought back Jalma and two other elf women , but failed to capture Cybriana , with three killed in the process . For their failure and deaths , Imgig Zu killed the chasme leader . When the City Guard of Waterdeep discovered his tower , Imgig Zu sent his gargoyles to destroy them . Imgig later used magic to contact his kin , who longed for release from " Selûne ' s Eye " . Imgig promised that he was close to succeeding and that he would soon release them to overrun Toril , an event he called the Great Awakening . Later , after the chasme had gone hunting for more victims and been destroyed by Cybriana and her companions , Imgig Zu observed " Selûne ' s Eye " glow like the moon , meaning that Kilili ' s sister was near his tower and had been found by the chasme . Kilili visited Cybriana , and lured her toward Imgig ' s tower . Imgig ' s gargoyles snatched up Cybriana ; when dropped , Kilili rescued her with a " ring of telekinesis " , and Cybriana was taken into their lair . Her companions , Priam Agrivar , Vajra Valmeyjar , Timoth Eyesbright , and Onyx the Invincible escaped the gargoyles and found other ways in . In the caverns beneath Imgig ' s tower , Cybriana was placed inside a " forcecage " as Kilili stood just outside . Their proximity , both to each other and to " Selûne ' s Eye " caused the gem to glow even more brightly and to swell in size . He revealed to Cybriana the secret of his connection to Kilili . Proclaiming his triumphs before an audience of his ogre minions , Imgig Zu used the combined powers of the elven women and the stolen wand of power to open the " Eye " and released his long - imprisoned people into the world , to overrun and conquer the Realms . Meanwhile , Cybriana ' s companions battled through the ogres and into the cavern , but were ultimately subdued . Imgig gloated , threatening to kill Priam with the same spell of death he ' d used to kill Ostus . But , just then , the roof of the cavern tore open and the brilliant light of the full moon — the workings of the goddess Selûne , via her avatar Luna — shone through , blinding the ogres . Cybriana urged her brother Priam to strike , and strike he did , slaying Imgig Zu in the name of their father . At Imgig ' s death , the " forcecage " faded , and Cybriana escaped . She grabbed Kilili and the two merged into a single being , the living key to " Selûne ' s Eye " . The merged being vanished inside the gem , drawing all of Imgig ' s people back within , saving the Realms from devastation . Description . Imgig ' s natural form was of a powerfully built humanoid creature , muscular and standing 7 . 5 feet ( 2 . 3 meters ) tall . He had scaly gray - green skin , red eyes , and a wide maw full of fangs . His great head bristled with curving horns : two protruded from the top of his head , two from the sides , and two from his jaw either side of his mouth . In the guise of a human - like being , he appeared to Selûne as a darkly handsome man with long black hair . In both forms , he customarily wore a white breastplate , greaves , bracers , and armbands , decorated with curling black designs and red gems in gold settings . Behind , he wore a long green cloak . Personality . Imgig Zu possessed a genius intellect , but was cruel , unpredictable , deceitful , and very evil . He had designs on conquest and slaughter . Abilities . Imgig Zu commanded the magical powers of a magic - user of middling level . His spells included " flesh to stone " and " stone wall " . He also knew a spell of death that could kill a being outright . He also possessed a number of other , separate powers , each usable once a day . With a talent for earth - based magic , Imgig could cast " animate " ( on stone statues ) , " earthquake " , " move earth " , " rock to mud " , and " stone to flesh " . He could also shape - change into the form of any humanoid being . Finally , he possessed a slight resistance to magic . However , Imgig seemed to lack any magical ability to travel between planes . Imgig was also incredibly strong . Origins . The world or plane that Imgig Zu and his people originated from was unknown , and it may have been an alternate prime material plane , one of the Lower Planes , or a small demi - plane . In the Song of Selûne , Luna ( in truth an avatar of Selûne ) described it as a plane with a forbidding blood moon palely glowing over a barren land . It was also unknown whether Imgig ' s people had the same powers he wielded , though they had the same appearance and shape - changing power , and were thought to be just as evil . Possessions . Imgig Zu wielded a " staff of withering " , a powerful staff that could magically age a struck creature , and even leave the struck limbs withered and crippled . He also held the wand of power seized from Selûne , in turn stolen from her father . Relationships . Imgig Zu was ruler of a race of people like him . In his plots in the 1350s DR , Imgig worked with Kilili , a drow sorceress and the literal key to his schemes ; and a led number of monstrous minion : a squad of chasme fly demon s ; a yuan - ti who organized the chasme ; a wing of gargoyles that guarded his tower ; and a legion of ogre warriors that waited in the caverns below . At one time , he also rode a wyvern .
