Slign

One of the intruders from the Under-leas has come to be so well known among the Orcs of Gundabad that it has earned from them a name – the slign. A slign is a dark, slimy, snake-like creature, ranging from five to twelve feet in length, and two to four feet in thickness. It is amphibious, able to propel itself in water by a broad tail, and to move on cave surfaces, even climbing to ceilings, by means of suckers on its belly and on two tentacle-like forelimbs, each two to four feet long. The most peculiar feature of the slign is its visual organ, a single eye mounted on a stalk above a wide mouth filled with dagger-sharp teeth. A slign is solitary, and may hunt in one of two ways: by remaining immersed in watery ambush, with only its eyestalk protruding above the surface, or by suspending itself on the roof of a cave, perfectly camouflaged and waiting patiently to drop on an unsuspecting victim. In either case, the slign's combined efforts at constriction, strangulation with its tentacles, and venomous bite (a 5th level poison) frequently prove fatal. Although the Orcs hate and fear the slign, they have never been able wholly to exterminate these cavern haunters.
