Oshu ' gun ( Draenor ) Oshu ' gun , said to be the largest diamond in the known universe by Gezhe in the original timeline , is located in southwestern Nagrand . Oshu ' gun is orcish for " Mountain of Spirits " . It is a great , white monolith that dominates the landscape , and instead of being jagged and irregular like other mountains , it is smooth and triangular . Deep within the massive crystal dwells a naaru named K ' ure , accompanied by ancient orc ancestors , the spirits of orcs who have passed on . Oshu ' gun is in fact a naaru Dimensional Ship called Genedar , and was the vessel K ' ure and K ' ara used to help the draenei flee Argus thousands of years ago , traversing the Twisting Nether until it crash - landed on Draenor approximately two centuries before the First War . Oshu ' gun is invariably linked to K ' ure . Around the time Oshu ' gun landed , K ' ure fell ill , rendering the ship useless . In the time following this event , the orc s came to revere the enormous gem . It became a sacred place and every year the orcs would gather there to celebrate the spring and autumn festival . The shaman would commune with their honored ancestors ( who , unknown to the shaman , came to dwell within Oshu ' gun to commune with K ' ure ) . Recognizing the orcish reverence , the draenei retreated from the mountain . As , it is presumed K ' ure was weakened by Oshu ' gun ' s crash and has been trapped within the ship for centuries . As his holy energies bled away over the centuries , a void slowly grew in his place — devouring the souls of those nearby . K ' ure watched helplessly as generations of orc spirits were consumed by this vortex . The novel " Rise of the Horde " , which was developed prior to the expansion , presents a slightly different nuance of K ' ure ' s relation to Oshu ' gun . Most likely , though , this story may not apply to new Draenor , as it involves the participation of the Burning Legion that has not yet come to the world in Warlords of Draenor . Unless the story changes again , another Naaru , D ' ore , was all but killed in the crash of Oshu ' gun . His remains should still be laid to rest by Velen and the draenei in the first crypt of what would become the alternate timeline Auchindoun . We don ' t know how D ' ore has affected this version of Auchindoun , yet . In the Draenor version of events , there was also an additional Naaru named K ' ara aboard the ship when it arrived on Draenor . However , K ' ara was ejected from the ship as it descended to Draenor , becoming The Dark Star . In Warlords of Draenor . In a conversation during the quest , Gul ' dan says to Cho ' gall : . Players later find Cho ' gall inside the sanctum of the naaru within Osu ' gun , in the midst of channeling a spell directed at K ' ure . Gul ' dan arrives and questions Cho ' gall ' s actions , demanding he hand over control of the darkened Naaru . Cho ' gall refuses , stating that he has learned much from K ' ure , but is finished taking orders from Gul ' dan . Shortly after , players witness the birth of the void god , transformed from the remains of K ' ure . Vindicator Nobundo and the player defeat Decimatus , but the sanctum begins to crumble around them , forcing them to make a hasty escape .
