There are hundreds of disparate Na'vi clans on Pandora. Some of the clans, including the Omaticaya, live in ancient trees that are two to three times the height of the Terran redwoods that once covered the Pacific Northwest.

The name Hometree is misleading, as the structure is actually comprised of a grove of intertwined trees of the same species that have grown together, providing for mutual strength and structural reinforcement. This, coupled with Pandora's low gravity, is what accounts for the immense height of Hometree. The Omaticaya revere this quality of Hometree as a constant reminder that a community is stronger and more resilient than the sum of the individuals who comprise it.

The circumference of Hometree is great enough to house dozens of clan members. The tree is honeycombed with natural hollows and alcoves in which the Na'vi sleep, eat, weave, dance, and celebrate their connection to Eywa. When a young Omaticaya becomes a man he is allowed to make his bow out of the wood of hometree also the hunters banshees live at the top of the tree for easy access. Hometree was recently destroyed by the corporation under the authority of Parker Selfridge and Colonel Miles Quaritch, forcing the Omaticaya to flee. Like many sacred sites on Pandora, Hometree sits above a large deposit of unobtanium.
