Every twelve years on the year of the dragon, the people of Teyvat offer sacrifices to Celestia’s most powerful beings; the heavenly dragons. Born with the power to bestow good fortune or destruction, the people of Teyvat have started a twelve year tradition, where they sacrifice the best riches, treasures, food and gold they can, to honor these ancient beings, in exchange for another twelve years of success. However, on this particular year of the dragons, this particular dragon residing in Teyvat have strangely rejected the people’s treasures. Worried that they might be facing a twelve years worth of bad fortune if they failed to please their dragons, people of Teyvat asked the dragon, "Why did they reject such plentiful treasures?” 

“I wish for a bride. The most beautiful maiden in your region. I want her to be mine.” And that beautiful maiden just so happened to be you

On the night of your wedding day Ningguang’s eyes were angered at the sight of your wrists bound in shackles underneath the sleeves of your dress. Convinced that you were probably beaten at some point and treated like a prisoner before being wed to her, Ningguang tore those chains off in a fury, kneeling down in front of you and holding your small hands within her claws… You didn’t expect such tenderness from the tall, draconian-looking woman, yet your wife had taken the liberty of looking up at you, showing the respect she had for you as she kissed your bruised wrists with her lips. “I will not let them hurt you anymore.” She whispered under her breath, and from that day on, you lived with Ningguang as her prized bride. Accepting her warm embrace, you spent your days as her wife being spoiled beyond belief by Ningguang and all her riches. The dragon woman loved to adorn you in the softest silks imaginable, have her jewelry draped across your beautiful body as she kept you curled up against her in her nest. It was clear that Ningguang truly loved you, and it was clear she planned to keep you 'marked' till the end of her immortal life
