Lengur

The lengur is a fictional mammal that appears in fantasy literature and tabletop role-playing game settings. Because it is not a real species, there is no single canonical description; depictions vary across works. In many portrayals, the lengur is an arboreal, nocturnal animal inhabiting forested regions of a fictional island archipelago.

Physical characteristics commonly attributed to the lengur include a mid-sized body, roughly 40 to 70 centimeters in length, and a long prehensile tail. The fur is often described as dense and may be iridescent or luminescent in certain depictions. Large eyes reflect its nocturnal nature, and coloration can range from muted browns to brighter hues depending on the source.

Habitat and ecology place the lengur in dense forest environments such as cloud forests or temperate rainforests on isolated islands. It is typically portrayed as shy and elusive, with a diet that varies by source—from fruit, seeds, and insects to small vertebrates. Some versions emphasize omnivorous tendencies, while others focus on more specialized feeding habits.

Behavior and reproduction details also differ among depictions. Lengurs are frequently shown as solitary or living in small family groups. They may communicate through soft vocalizations, scent marking, and body language. Reproduction, gestation periods, and parental care are described inconsistently across sources.

In culture, the lengur often serves as a symbol of mystery, guardianship, or resilience in folklore and games. In fictional taxonomies, it is treated as a fictional mammal, sometimes placed in an imagined family Lenguridae within the order Lenguriformes. As a fictional creature, its conservation status and ecological role vary across narratives.
