Before she does...

As she slept, Katara began to dream of being in the forest. Walking through the trees, she came upon a clearing. A clearing occupied by a huge creature. It looked like a mix of a bird and an insect, all brightly coloured red and pink. Six legs ending in bird claws, insect wings under it's bird wings, a bird's head with an insect's segmented eyes.

"I am the spirit of love and desire, Kama. I have heard you wish, and given the need for the airbenders, will help you with it. By gifting you and your husband and his wives with my power." said the spirit in a deep voice which vibed through her body.

"What do you mean?" she asked, curious.

"When you wake up, and explain your desire to your husband, my gift will allow him to love and desire it too. Then when either of you explain it to a woman, they will desire and love the idea. All of you will feel great love for each other with all of that brings. With that, I hope that the number of airbenders will begin to rise. Will you accept my gift?"

Katara considered before saying, "Yes, thank you."

And so the image changed to the potential future of Katara, her husband, her fellow wives and their kids. Soon morning came and the woman had to awake to a new dawn.
