Alliance
Their marriage was arranged, predetermined by the spirits themselves.
They were from different tribes. A marriage between them would bring them together to form a great union, merging two tribes into one.
Princess Korra was but three years old when she was matched up to be engaged to Tarrlok, the neighbouring chief's nephew.
Tarrlok would visit the princess's tribe, to see what the land was like, and to see Korra as she grew year by year.
Most girls would be calm, reserved, and sweetly gentle. Korra, however, was rambunctious. Energetic, and had this… lively spirit about her. She had the makings of a warrior, rather than that of most roles of tribal females.
She often rode on her horse, Kuruk, and explored the land with her dog, Naga. Despite her untamed nature, she was greatly in tuned with the spirits through the animals.
They grew into great friends, Korra still ignorant that Tarrlok was her betrothed. Whenever she saw him, he was her 'great big friend'. They had many competitions together, one of them being horse racing, which she always beat him at every time.
"Do you have to leave so soon?" An eleven year old Korra stood by the tipi as she watched her betrothed pack for his journey.
"The buffalo are moving quickly," Tarrlok chuckled. "We must catch up to them, or we shall have nothing for the winter."
"Bring me back something."
"Bring back what?"
"A wild lily. From the pond. They only grow this time of year."
He smiled as he went to kiss her forehead. "That, I shall get for you. And one day, when I return and you are of age… I will come back and marry you."
She blushed as he held her in an embrace.
"Promise?"
"That… I promise. With everything I am."
