The Legend of the Uluu Thalongh by Rhue del'Asandro

Of all the legends whispered about the monster-infested swampriddled jungles of Chult, the most eerie is that of the Uluu Thalongh, a name whose meaning has been lost along with the tribe that bestowed it. The Uluu Thalongh is a huge, ancient, and malevolent flesh-eating beast. A wierd, tuneless piping always marks its approach.

When it closes on its intended prey, the Uluu 'goes within' jungle plants and trees, causing them to ripple and bulge. These swellings move swiftly to branches, from which they burst forth as huge jaws at the end of tentacles - eyeless jaws that see prey perfectly, snapping and tearing until all creatures nearby have died or fled.

Even cabals of wizards casting fiery and explosive spells that obliterate miles upon miles of jungle have failed to destroy the Uluu Thalongh. More frightening is the tendency of this mysterious predator to lure prey to itself by causing beings to speak for it.

The Uluu can then convey its own thoughts and mental control through the speaker. Even creatures that don't normally speak can hoarsely whisper words in an attempt to lure humans to its jaws.

Sometimes speakers plead for help or shout mock cries for aid from afar - but more often they pose as aides or companions whom the Uluu has already slain. Who or what the Uluu Thalongh truly is remains a deadly mystery.
