Hollow world
In Liir fiction, the idea of an inner ecosystem powered by the core of the planet in replacement of the sun is a persistent, if laughable idea. The great thing about fiction is that it can explore ideas that aren’t possible in real life.
On the other hand, the liir are quite good at what they do, and an ecosystem is child’s play for the resources of the Biocollective.
The Hollow world project is a large scale structure, capable of being built anywhere as the outer shell can be placed fully underground, underwater on land and partially buried or even in orbit with sufficient effort, where ever there is a sufficient amount of free realist state.
The Hollow world is a 50km radius orb, Made from various layers of carapace required to hold the sphere in tack at its size, as well as regenerated any damage that might occur, either on the inside of the Hollow world, or the outside.
Afterward, inside the layers of building carapace varies layers of sub organism are set. Near the top are sets of light energy or any other form of energy that is deemed necessary. Heating organism’s, filter organism, watering organism. Everything needed to create a self sufficient ecosystem within the hollow world that will be thriving with life.
Afterward, The Hollow world is filled with Materials and various organic life forms. Everything from scavengers, tree’s, fungus’ mold, ferns, herbivores and carnivores. An entire specially designed ecosystem from the ground up.
The plants consume outside resources and absorb energy provided by the workers of the facility, similar to the sun eater. These plants form the lowest run on the food chain of the ecosystem, which are eaten by the various herbivores. The lifeforms have been specially modified; Their intestinal system and digestion system is the biological equivalent to a purification plant for organic matter. As the nutrients and materials that had initially eaten by the plants are passed up the food chain, they are furthermore refined.
The excrements of these life forms take the forms of various quality levels of organics. Simulated rainfall and specially designed small drones, designed to be unappetizing to the ecosystem creatures, carry the excrements away to be filtered from the Hollow world resources and collected.
The entire hollow world acts a near self-sufficient refinery, capable of producing large amounts of organics of a variety of purity’s, forms and quality.
Of course, as living creatures breed and die, random mutations are always a possibility. The worst-case scenario would be a random mutation that changes the digestive system and the excrements, making them useless for the purpose of the hollow world.
This has been prevented via a change in the sensory organs and brain of the various species. Creatures that are not producing the correct substance, smell sick to other of their species and especially delicious to carnivores higher on the food chain. This should prevent the mutant in question from breeding and will quickly be eaten. A similar mutation takes place for those without these modifications.
Other then that, Mutations are merely categorized and are generally left alone.
In the event of a mutation that benefits the system, the mutation will be categorized, encourage in the current Hollow world and used for any future construction.
The hollow world model allows us an easy test bed for promoting a beneficial mutation we desire and for the testing of a variety of bioforms under a massive assortment of the condition, Requiring only a modification to the brain of the creatures and the digestive system for them to be viable. This makes it rather useful for the stress testing of any new biological forms we require.
