Some may find this tale familiar as I have completely rewritten it to be... more in canon with Legend of Zelda.
The story takes place in both Hyrule and Termina.
Please note that the clans of Ikana are to be regarded as the Termina equivalent of mix between the Dark Interlopers and Twili from Hyrule.
Timeline wise this takes place a few years after Majora's Mask, but eras before the events of Twilight Princess.
Our tale began long ago, before Majora's Mask tried to throw the moon into Termina…
Back in the era of arcana, where Termina had mastered all manner of sorcery and magic.
The Terminans divided into the commoners and the magically gifted, the Ikana.
The Ikana, with their knowledge of light, built their kingdom in the eastern valley.
However as their wisdom grew they also became entwined with an obsession of darkness.
Soon enough the kingdom was divided between those who worshipped the Golden Goddesses and those who worshipped the Giants.
The followers of the Light proudly kept the name of Ikana who sought to keep their counterparts confined to the Eastern Valley.
The wielders of Darkness became known as the Dark Interlopers or Gomess who grew obsessed with the Twilight Realm.
What followed was inevitable as each side regarded the other's gods as feeble and weak compared to their own.
Out of hatred, the Gomess constructed the Stone Towers to act as a portal to the sacred realm to spite the Ikana.
The Golden Goddesses intervened when they cursed their temples and tried to damn the Gomess.
This intervention did not end the tribe, as it merely opened a portal to the Twilight Realm, the home of the wild deities.
It was in this land they discovered the mask of the Man Eater, the remains of a primal god.
The emergence of this mask only ignited a long brewing feud as war was declared.
Neither the Ikana nor the Gomess were willing to negotiate.
They did not even realise the Stone Towers had created a gate to Termina.
They did nothing as various wild deities migrated to Termina amidst the confusion.
They did not stop fighting, even as the plague bringer, Bellum, invaded Termina.
One Gomess proved to be different as she was Majora, the chosen of the Eastern Giant.
Equipped with forbidden knowledge of darkness, she joined forces with the Deku, Goron and Zora to banish Bellum.
She led them to become the chosen of the remaining Giants and to be capable of calling upon the masked shadows of each primal god.
They were victorious in their endeavours, they banished Bellum and saved Termina from a terrible fate.
Upon her return to Ikana, Majora was still faced with the same war.
Although her recent conquest had made her the target of a sinister plot by Arch Mage Zant.
Her soul was shattered as he tore out her malice to become an imp for him to control.
Donning the mask of the Man Eater, the imp played along until the opportune moment.
When both the Ikana and the Gomess leaders were gathered on the battlefield.
The Imp unleashed a curse upon both clans, using that accursed mask as a catalyst.
The Ikana were mutated into the undead, doomed to be shunned by their beloved their goddesses.
The Gomess were exiled to the Twilight Realm to suffer a hellish fate at the hands of the demons that dwelled there.
In Ikana's darkest hour, Majora confronted her other self and the monster influencing her.
She played the Song of Healing and sealed away the demonic man-eater as well as her imp into its mask once more.
For reasons unknown she then plunged into the abyss of the Stone Towers, sealing the stronghold of her tribe from unwanted visitors.
The mask of the man-eater gained a new name that day, Majora's Mask.
Many eons have passed and Majora's Mask had surfaced once more.
This time falling into the hands of a broken deity, who had lost all sense of their self.
Out of loneliness and driven to the brink of insanity by the Man Eater, he sought to crash the moon into Termina.
The puppet was saved and the Man Eater was thwarted once more by a hero from a distant world.
The lingering ripples of this event have flowed through time.
As Majora's Mask had bound the Giants to their wrathful shadows, Bellum's imprisonment beyond the veil of time and space had also weakened.
Although the parasitic monster could not return to Termina, it was not forbidden to manifest in the realms of the Golden Goddesses.
And so another game among the primal deities has begun…
