Description

Many have wondered why a unit of measurement called a worm (and its subunits called segments) exist in Mechanus. Little do they know that the answer is linked to a bizarre and fascinating creature."

— From Nimal Amur's A Field Guide to the invertebrates of Mechanus

The 5.9176 pentranomeker worm is a strange creature that dwells only in Mechanus. It's name is a shortened version of the name the modrons gave it which was, A Large Pseudo-Arthropodal Annelid Of Approximately 5.9176 Pentronomekers In Length, Weighing Approximately 2 Tons at Maximum Weight, Which Feeds Upon Non-native Non-living Material.

This creature resembles a giant inch worm with a body divided into exactly 20 even lengths segments. its soft exoskeleton is largely green in colouration with amber disks. It has a snout similar to that of a star nosed mole surrounded by a circlet of black eyes. It has no mouth, instead a sticky disk is located on the underside of the head segment. The tail segment is encased with metal and used for defence.

Combat

When threatened a pentranomeker worm lifts up its tail segment threateningly and uses it to club his enemies. If a group of six (a hextet) of worms is threatened they form a circle with their heads facing the middle and all raise their tail segments, if the threats do not cease they send their tails crashing down on the unfortunate soul.

Habitat/Society

Most of these worms are domesticated creatures used as mounts (they travel at the average human walking speed yet never seem to tire), measuring devices, and clean up crews.

Wild pentronomeker worms (like the domestic ones) are solitary unless six meet up, then they travel in a hextet until one dies and they go their separate way or division makes the group have more than six members. Wild worms migrate from portal to portal feeding upon non-living material brought into Mechanus such as dirt. The non-living material sticks to the worms feeding pad and is absorbed by diffusion. An amazing thing about these worms is that the amber coloured disks on their skin contain small lines of different colours, these lines recorded how far and how long these worms travelled in a straight line, thus the worms have a built in record of their migration routes. Since these worms usually travel in straight lines most of their movements have been recorded by fastidious Guvner zoologists and the like. Pentronomeker worms reproduce by division. One worm splits along the middle from front to back into two evenly long worms.

Ecology

These worms have a vital function of keeping the metal disks of Mechanus clean by eating foreign material. Oddly enough they cannot survive outside Mechanus.

The Outlands

More is known about the Outlands than many other planes put together, but there are also a great many mysteries to be encountered here. Not least is the Infinite Spire itself, a tapering pillar of dark rock that rises from the flat plains of the Outlands both suddenly and with eyewatering proportions. The plane itself can be divided into three portions: The Spire, the Gate Towns, and the Hinterlands... Find out more in the Outlands part of the planes book…(coming soon…)
