Nentuk is a weapons artisan who was born in the Hollows but has lived most of her life in the Spires. She has a gift for woods, waxes, shellacs and twines, creating intricately beautiful, yet practical weapons for hunters - both to feed and protect her clan.
Her manner and work ethic means she is held by Tsu'lo as an exemplar of clan values; stoicism and directness in the trying environment of the Spires. She slightly resents the weight of this responsibility, craving to be part of the wider Na’vi world. The arrival of the Sarentu offers her hope that she will get to explore.
The Sarentu meets Nentuk in the Sheltering Falls after meeting the Ke'awa Kame'tire. The weaponsmith will gladly share her creations with the newcomer. After that, she can be traded with.
