The death of Umarak during the Toa's final quest left Okoto's elemental forces imbalanced. Without him, the element of shadow was left at a deficit and the other elements a surplus- such conditions would not sustain Okoto.
Meanwhile, the dark energy of the shadow realm was at an all time high; having absorbed The Hunter. All that needed to occur was a slight rift, and darkness would flood in to its rightful place among the forces. It was time for Makuta's plan to reach phase two.
He very well knew that without a vessel, he could not exist as more than a mere shade of his being on Okoto's plane and would likely dissipate. However, with the need for a new creature and deficit of energy to form one, a new being would be born of the shadow realm as soon as the rift was opened. All that remained was a trigger to break the veil between the worlds and that was already within his grasp.
Makuta didn't intend to escape during the final confrontation with the Toa. While the heroes were realizing their destiny, he was gathering the remains of his forbidden mask. They would seal his portal in vain, as was foretold in the prophecy, and Makuta would be ready to launch his escape.
Before his empire, Makuta stood a Mask Maker. Soon, he would become one with the darkness and ascend to something much greater. Unbeknownst to his brother, the supposed heroes of Okoto, and all that had stood in his path, he was about to not only begin his true conquest of the island- but become one with Okoto itself!
He thrust open his grasp, the six shards of his broken mask drifted into the space before him and converged. Gilded and ornate, the mask was as stunning a sight as ever- his greatest creation. It rippled, shuddered, and imploded on itself and the tear expanded beyond the bounds of where the mask once floated. Makuta could feel the realm itself begin to flood through the hole. He sacrificed his will, his instincts, his judgement to the rush, and let it carry him.
Makuta opened his eyes for the first time since his death. Two ominous crimson red moons loomed above, as though to celebrate his reincarnation. The tyrant eyed his new form; it was imposing and sturdy with a smooth metallic carapace and an abundance of white spikes. At long last, a form worthy of his soul.
Makuta stood at the cusp of his victory, the Toa banished to the stars and he with a form and element all his own. Mask maker no longer, he is Makuta The Shadow Seeker.
Makuta's Hammer of Souls is powered by the spirit of his former minion, Kulta the Skull Grinder. Makuta saw fit to keep Kulta's head chained on as commemoration of sort, but also as a handy place to plant herbs needed for reanimation rituals.
I will be entering this into the contest(probably soon after I post this, actually) and am pretty interested in hearing what you folks think. So, as always, comments, criticism, praise(if you see fit) are really appreciated!
Thanks for giving my moc a look!
