Bladder lanterns, or tsmisnrr, ‘nectar lamp’, are used as light sources in Na’vi villages, or wherever light is needed. They come in different forms, consisting of the stomach, or thin-skinned internal organs of various animals, dried and sewn with twine and leather.
Though the Na’vi have excellent night vision, they enjoy the calming glow provided by these lanterns. The organ’s interior is filled with nectar and other food to attract indigenous glowing insects similar to fireflies, such as hellfire wasps, called zize’. Those insects, in turn, attract more of their kind, perpetuating and increasing the lantern’s glow. Bioluminescent caterpillars can also be used as a light source in a tsmisnrr. They are found throughout kelutral as lamps, but some can be carried or worn.
