Long ago existed a myth of two halves, it is said that there was once a boy born with great power and with a blood lust like no else has ever seen. it is said that he would eventually control all the sand within Shurima and bludgeon all within it continuously till all that remained was Blood, Bone and Death.
It is also said that a great and mysterious sorcerer was able to separate the once whole boy into two beings by first casting a sleeping spell on him. one of them took the form of a boy and the sorcerer gave all the power of the boy into that body. the other was made of sand and the sorcerer put all the blood lust of the boy into that body. he then sealed the both of them high above the sky in a seal, that only those more powerful than himself could break, away from their power.
What the Sorcerer didn't expect was the creature he sealed waking up. even high above in the heavens, people could hear it the loud grumble, the continuous sound of Bam, Bam, Bam and finally the Shriek of something monstrous. it is said that in this place of Shurima that the sand flies up into the air as if called upon by the creature that cries from up above.
And so time flew and flew, first decades, then centuries, coming past eons. The one that sleeps kept on sleeping and the one that woke kept on banging. the prophecy of Shurima's end completely forgotten and the Myth of two halves no longer spoken and it was then when no one remembered who they were, that the one that slept awoke and the one the banged broke through.
