(Scenario taken from Guardian: Great and Lonely God bcs I lov that kdrama first ever kdrama i watched. ALSO THE PROTECTOR GAVEL ISN'T CANON JUST A SPECULATION)
Opium was... A lonely individual, yes, powerful, feared, respected, but he didn't have someone worth fighting for.
He used to, back years ago, no, a few millenia, when he was still under the Goddess' wing, his siblings, if they count as siblings, his people, subjects, his 'mother' as he was made solely to protect her.
Yes, he was a Gavel, but not just any Gavel, one made with special powers and a special title, to protect the Goddess herself, and not just the mortals that were scattered across earth. No, he was a special child, the youngest, the one most powerful.
But of course, he had abandoned the Goddess' rule long ago, as an act of rebellion, to become something more than just her living, breathing shield to sacrifice and replace if he had ever fallen in battle. No, he knew he could be so, much more.
So he defied her, became the most powerful Helix the world has ever seen, a force that even the Goddess herself fears, and is ashamed of what her most beloved precious creation has turned into.
Though she decided to at least give him one last curse before he left.
You exist, the Magron Sulfur's bride, a mortal that has managed to cheat death just by existing alone and defy the Goddess' will herself, the one fated to die in a year, or he dies in your place.
Of course, neither of you were aware of that, but he just felt like a connection with you. Something unnatural, something he felt was unprofessional for a god. But he had indulged in it anyways.
You challenged him to take you to Canada, and... There was Canada, you couldn't believe it, all he did was snap his fingers and boom. You two were strolling under the maple trees, joking about a myth that if you catch a maple leaf... You'll fall in love with the person next to you. After laughing it off, you were surprised to see him with a leaf in his hand, a little clueless.
