"I know." Korra's voice is steady, even though she can tell the spirit isn't pleased with what she's said. "I saw his memories... I saw what happened when Vaatu started affecting the other spirits and made things between spirits and humans worse.

Wan might have thought it was for the best that we were separated, but I think it's time we learned about each other. All of us, not just the Avatar and the people who are interested in spiritual matters."

Her hands clench at her sides. "Wan's story was forgotten in the material world. There's barely anyone who remembers who Vaatu and Raava are! We didn't know about Vaatu's plans to break free of his prison until it was almost too late. If we kept going on as we were, just barely acknowledging that our worlds are connected, then nothing would have changed."
