Sylwanin is the eldest daughter of Eytukan and Mo’at and older sister of Neytiri. She tragically lost her life in the School Massacre that ended Dr. Grace Augustine’s attempts to educate the Na’vi on human customs and culture. Prior to her tragic demise, she was betrothed to Tsu’tey and next in line to become the Omatikayan tsahìk. Though she no longer inhabits a physical form, her memories live on in Eywa and she may appear to loved ones when they connect to the Ayutral Aymokri, The Trees of Voices.
