Vëtiš

The Vëtiš are the 8 legs attached to an Ibrófeneð. They are one of the most complex systems known and the part of the body most responsible for motor movement and manipulation of other objects.

Leg Anatomy

The legs are composed of three parts:

• Vëtiš-Húrobü: An extremely flexible yet fragile cylinder of silicon that acts as the bulk material in the leg
• Vëtïš-Mëta: A dual series of rope-like appendages that attach to the top and bottom of the leg
• Ýyr-Vëtiš: A thin layer of skin that bundles everything in one package.

Vëtiš-Húrobü

Main Article: Vëtiš-Húrobü

The Vëtiš-Húrobü is the core part of the leg, accounting for 60-70% of the total leg mass. It takes the form of a cylinder of silicon and carbon, whose combination results in a very flexible yet sturdy material. In addition to serving as the leg's 'bone', that is, its structural frame, it is also the main transport of nerve signals and nutrients for the other two layers, which it moves mainly by channel systems within the material. Due to the lack of muscle within the Vëtiš-Húrobü, these are fed only by gravitational motion. The channels themselves are a maze-like network which regularly branch off to gel-like connecting links that connect the Vëtiš-Húrobü with the other two layers. These links occur at a rate of 10-15 per square centimeter, resulting in a very tightly-knit composition between all three layers.

The Vëtiš-Húrobü is very unique in that it requires the most carbon, and is the main reason behind the necessity of carbon in the Ibrófeneð diet. Typical bone in the rest of the creature consists of 97-99% silicon and 0.5-2% carbon, but in the Vëtiš-Húrobü, it consists of 80-90% silicon and 9-15% carbon.

Vëtiš-Mëta

Main Article: Vëtïš-Mëta

The Vëtiš-Mëta, meaning the Twisted [part of the] leg, is the main muscular portion of the leg, and thus the part most responsible for locomotion, both of the leg itself and of the foot. It consists of two separate sets of thin, rope-like material, each 2-3 centimeters thick, that connect to the thin ring at the top of the leg, run down the entire length, and connect at a similarly-thin ring separating the leg from the foot. Each of these rings has terminals where both sets of Vëtiš-Mëta are connected in alternating order. However, while one set of muscles is connected to the same terminal as that of the other ring (resulting in a straight up-and-down arrangement of muscles), each of the muscles in the other set is connected to the terminal two places away from its corresponding place in the other ring (twisted). This is the arrrangement of the leg muscles; the straight up-and-down set serves to constrict and relax, pulling the leg in different directions, while the twisted set is deactivated and instead serves as extra stability for the leg. These two are alternated by a special muscle attached to the lower ring, which rotates it such that the twisted set is now straight, and the straight is now twisted.

Both sets are equally capable of moving the leg in all directions, but in any single instance, one set is over the other, and this doesn't change regardless of which is straight and which is twisted. Despite having the same capacity to move the leg itself, the difference lies in the foot, where the outside set controls the claw arrangement while the inside controls the suction cup arrangement.

Ýyr-Vëtiš

The Ýyr-Vëtiš is the outer skin of the leg. It measures 1-2 cm in thickness, and is the thickest type of skin the creature has.
