Eli'ä, Neytiri's older sister, was always a woman of the forest. She was never home, always staying up on the trees with animals by her side. When her sister found her mate and got to know she was pregnant, she knew she had to give a hand into helping her clan. So, she started learning how to be a Tsahik. And as years went by, when the sky people started attacking again, she was taken hostage alongside a young boy named Spider. Though, she would have never guessed she was going to fall in love with the man who kidnapped her.
