When the winter came, the whole village gathered around the fire to tell tales against the darkness in the long-houses. The stories could come from the Beginning, or from the last Solstice. It didn't matter when really, as long as it was good. The ones that came from the hunt where Korra's favorite. The skill, deftness, and endurance of her fellow tribesmen were made legendary with time, scars, and meat. (Lots of meat; tasty.)
The tales from the Hundred Year War left her ... unsettled. Even as a little girl, she had the sensation of knowing how these stories were going to end. But the one that she almost hated was the Siege of the Northern Water Tribe. The nights always felt colder after hearing that chronicle, and the pull of the Ocean felt dark and scary.
The Siege was an important story, and it was told many times during Korra's first sixteen years of life. Gradually, she began to understand why it upset her. Yes, she was sad that Princess Yue kind of died. Most kids in her age group had had a sniffle over that. The part that upset Korra specifically, was that she had been the single person that could have saved them all. It was cruel, and it was unfair to place so much on the shoulders of a single being.
Every year that drew closer to the revelation of the Avatar left that feeling of unfairness coiling tighter in her gut.
A/N This was a request from a couple weeks ago. Fingers crossed for how it came off.
