High Imaskar High Imaskar stood on the shattered ruins of Mulhorand on the eastern shore of the Sea of Fallen Stars . It represented one of two nations of Imaskari survivors in the 15th century DR . History . The great empire of Imaskar was destroyed when the gods of their slaves , the Mulan , rose up and shattered the empire . Some of the Imaskari retreated to Deep Imaskar in the Underdark beneath the Hordelands . The Spellplague had two benefits for them , scouring the Mulan from the map and cracking the Great Seal that kept Deep Imaskar safe from the outside world . Explorers from Deep Imaskar set out to see if the Mulhorandi persisted , only to find another group of descendants , under the wizard Ususi Manaallin , had relocated the old Palace of the Purple Emperor to the barren Mulhorandi lands and founded the city of Skyclave . Deep Imaskar was subsequently attacked by ancient living weapons of Imaskari design and only the timely intervention of Empress Ususi and the vengeance - taker Iahn Qoyllor saved the beleaguered city . When the threat had been dealt with , many of the younger Imaskari of Deep Imaskar left with Ususi to support the growth of High Imaskar . Geography . High Imaskar claimed the ravaged lands that the Mulhorandi kingdom once sat on . The Spellplague scoured the lands , reducing them to a blasted range of mountains , chasms , and earthmote s . The terrain made transportation all but impossible by anything but air . To the east , across the Dragonsword Mountains , lay the Plains of Purple Dust , a new extension of the Raurin Desert beyond . The highly inhospitable region was plagued by large purple worm s and dust devil s . Society . High Imaskar was divided into the cities of Skyclave and Gheldaneth . Skyclave was a miracle of magic and an empire reborn . Gheldaneth was the last remnant of the Mulhorandi kingdom but existed as a vassal to the revived Imaskar . Skyclave attempted to recapture the grandeur and glory of the original Imaskar empire with two significant changes . Empress Ususi ' s first imperial decree abolished the Imaskari tradition of slave - holding and outlawed slavery on pain of death . She then established the Body of Artificers , Planners , and Apprehenders as a foil to her power . Skyclave itself was a huge single tower , enchanted to be larger on the inside than the outside . It was a symbol of the former might of the Imaskari wizards and it housed the revived Academy of Imaskar . Gheldaneth , in contrast , was a failing metropolis where the remnants of the Mulan people found themselves unable to resist the renewed might of High Imaskar . While the edict banning slavery also applied to the vassal city of Imaskar , a second edict was enforced in Gheldaneth prohibiting the worship of the old Mulhorandi pantheon . The local detachment of vengeance - takers had to put down several revolts led by priests of the illegal religion . The majority of palaces , temples , and academies of old Gheldaneth were submerged in the devastation of the Spellplague , and a large number of treasure hunters occupied the city , hoping to plunder the sunken quarter of the city . Trade . High Imaskar maintained trade relations with Deep Imaskar , but the backward and introspective sister city grew jealous of its brighter sibling and that resent was festering . High Imaskar also recognized the need to have allies in a world that didn ' t quite recognize it as a full kingdom yet . To that end , they give favorable trade deals to the new dragonkin kingdom of Tymanther to the west . Trade in High Imaskar was accomplished via the huge redwing insects , bred by the Imaskari to carry passengers and cargo through the harsh lands .
