The Malmuria are an alien species native to the "tenth planet" Malmur, which occupies a highly elliptical orbit in the Solar System. The Malmuria raid Earth for food once every 2,006 years, when Malmur passes by Earth.
Anatomy & Physiology Edit
Malmuria are highly unusual creatures of recent aquatic ancestry. They have a black, ovoid body roughly the size of a human torso, with a cluster of ten tentacles emerging from each side. A third set of ten tentacles sits at the bottom of the body, which the Malmuria use to walk. Malmuria have ten eyes, each one on a retractable stalk that can be withdrawn completely into the body.
Malmuria breathe methane in place of oxygen. They can consume the same kinds of molecules for food that Earthly life does, although they must modify them first in unspecified fashion.
Malmuria are omnivores. Due to their homeworld's devastated state, they feed exclusively on paste made from organic matter harvested from Earth.
Reproduction & Life Cycle Edit
There are male and female Malmuria, who mate with specialized tentacles. The natural lifespan of Malmuria is unknown. While many Malmuria are several tens of thousands years old, this is because they spend most of their lives in cryogenic hibernation, only emerging for less than a year at a time.
The Malmuria inhabit Malmur, the tenth planet of the Solar System. Malmur is a small terrestrial approximately twice the size of Earth's moon. It is originally of extrasolar origin, and found its way to the Solar System after being ejected from its original system under unclear circumstances.
Malmur has an extremely eccentric orbit lasting 2,006 years. Its orbit takes it thousands of AU into space at aphelion and closer than Venus during perihelion. The orbit makes two close passes by Earth near perihelion, during which time the Malmuria invade Earth for food.
Atmosphere & Climate Edit
Malmur's atmosphere is thinner than Earth's and consists mostly of methane. It is usually extremely cold, and no weather events are ever observed on Malmur.
Malmur's terrain consists mostly of dusty plains. When it approaches the sun, solar panels unfold across its entire surface, concealing the planet from Earth observation and gathering vast amounts of solar energy. Most Malmuria day-to-day life takes place beneath these solar panels.
Malmuria are an advanced spacefaring species, with technology surpassing that found on Earth. However, they run an extremely tight energy budget, greatly limiting their industrial and offensive capacity.
Malmuria spacecraft are black, ovoid vessels about the size of football stadiums. While propelled by unknown, gravity-defying means, they are incapable of relativistic or faster-than-light travel and seem to move no faster than terrestrial rocket spacecraft. They are used mainly for harvesting food and energy. While technically unarmed, these harvesting capabilities can still be weaponized to deadly effect.
Due to Malmur's extreme deficiency of energy and biomass, Malmuria technology is built around the acquisition of these resources. Malmur is blanketed from pole to pole with solar panels that open when it approaches the sun. Malmuria ships emit a field that drains electrical energy from nearby objects, robbing them of function; vehicles affected in this way fail instantly, often killing their occupants.
The most important Malmuria harvesting tools are their nanoharvesters. These tiny machines are dropped in billions-strong black clouds onto areas rich in biomass to consume and process it, excreting unusable components. Afterwards, the ships return to pick them up. While incapable of replication or even independent movement, they are nonetheless devastating, able to lay waste to immense swaths of land and kill millions of people.
