White Shapes

White Shapes, called Geier in the EU, are carnivorous predators that began to appear after the Great War. Many believe they were a final weapon unleashed on the world in the waning days of conflict, a doomsday device meant to ensure no one truly won. As to what side may have deployed it is lost to time.

Physiology
White Shapes typically grow no larger than half a meter tall, and two meters long, taking on the appearance of a fish-like entity. They possess two small arms which are stubby and appear to lack musculature, but can tear flesh and limbs from marked prey in one swipe. Their teeth are flat, yet possess a sharp edge that rivals that of obsidian, and are nearly as strong as steel.

Their features are defined as "flat", and even "bland." While their mouths are always in evidence, showing a permanent wide swath of flat teeth, their eyes are locked in a squinting position, and their noses are flat. They do not seem to possess ears, though they are capable of hearing.

White Shapes have a powerful sense of smell, particularly able to detect blood from miles away. They will swarm and go into a frenzy if enough blood is spilled where they can get to it, even to the point where they continue to kill after eating their fill.

Though they have no wings, they are able to fly under their own power through means unknown. Some have hypothesized that their flight is linked to a spatial anomaly contained within each White Shape's body. They have been noted to be bigger on the inside, bleeding more fluid than their bodies should be able to contain when cut or pierced.

Though many scientists have attempted to label them with a more accurate name over the years, the term 'White Shape' has stuck. Many believe they were originally named due to the Shapes' incredible speed, capable of moving so quickly that it is difficult for the human eye to notice anything about them beyond a blur of white as they fly by.

The Rules
To further the mystery of White Shapes, they all follow a set of rules that no one can explain, but the general population of the world has sought to exploit in order to survive. The rules are as follows:
 * Don't go out at night. White Shapes appear only after the sun has gone down.
 * Keep the doors closed. They can only enter a home or building if there is an open door. They will ignore all other openings, such as windows, or even structural damage. They will not attempt to open a door, so long as it is fully closed.
 * Cover up. A White Shape will always attack exposed skin first. Though covering up will reduce the chance of being attacked, it is not a guaranteed method.

Habitat
White Shapes exist all around the world, though they are more dense in the areas around the City-States. Berlose and Gregos are both noted for having a particularly large population of Shapes, while areas in the Wastes between the two cities have seen a decline. Many believe this is the reason why there are so few, if any, Shape-related deaths among Senir nomads, though this could be due to superior preparation.

Shapes rest in areas of guaranteed darkness during the day. They generally prefer sewers and saves, though have been known to sleep in buildings ruined enough that they no longer possess entire walls -- and therefore make the structures immune to their "rules" -- if available.

Entering a White Shape habitat is largely considered folly, even during daylight hours, and as such, there is little to no information on their social or sleeping habits.

Diet
White Shapes are exclusively carnivores. Though they relish in the kill, they will consume any meat, even if it is scavenged from a rotted corpse. While they appear to be pack hunters, it is largely believed this is only a coincidence. Due to their incredible speed, they just happen to come across prey at the same time, and frequently compete with one another for a kill.

White Shapes can and will consume others of their kind, particularly when they are in a frenzied state.
