Civilization Name: Tide
Mortal Race Name: Cicadas
Mortal Race description: Cicadapeople that form social groups, with a twist. The nymphal cicada are active ambush predators(also proficient diggers), a favoured tactic being to dig large pits and chasing prey animals into them, supplemented by a diet of tree sap. The youngest cicadas, and thus smallest and slowest have to be particularly cunning and reliant on traps, instead of using their physical abilities to simply hunt down prey.
This led to a strange evolutionary quirk, where the first cicada instars have the highest intelligence, with the intelligence slowly deteriorating with each molting, until the most drastic metamorphosis into the imago, gaining wings, switching from being omnivorous to only drinking tree sap, and having only the intelligence of particularly bright animals. The flights of the cicada, and their chorus songs are both extremely beautiful to the younger instars, and a source of horror at their own inevitable regression, with only the wonder of flight and laying the eggs of the next generation as small comforts of adulthood.
Other: Sometimes non-paragons can temporarily enter waking dream states, especially during periods of high stress, particularly during battles. Generally they just gain the skills of their previous lives, rather than any mystical powers. This lesser waking dream state is generally called a "martial trance".
Civilization culture:
Tide Religion: They believe that after death, cicada are reincarnated anew. They liken life and death to dreaming and waking. Just as a night's sleep may be filled with dreams of powerful drives, passion and wonder, only to slowly fade like mist before the sun once awake, so death is a time of sleep and dreaming, from which cicada awake once they hatch, slowly losing the power of the dream, and their intelligence with it, forgetting it's wonder, until they sleep again. Each nights sleep is seen as a microcosm of this larger cycle of life and death, a temporary return to the dream, yet even more ephemeral than the sleep of death.
A somewhat more complex and subtle expansion of this concept, is the cyclic nesting of dreams within a dream, with your previous life in fact being part of the deathdream for this dreamlife, that is part of the deathdream of the dreamlife after it. As such, along with the dreams themselves, you are forgetting your memories of your past life.
There is another sect which believes that each cicada moulting was part of a slow ascension to a higher plane of existence, with the lowered intelligence being caused due to getting less and less in tune with the base lowly current plane, until finally the adults fly up past the clouds, past the sky and sun and become spirits.
Method of Ruling: A child shall lead them.
Sometimes a particularly large and special type of cicada egg is lain, a Paragon. These Paragons can survive being broken out of their eggs before they hatch naturally, thus entering the waking world while still being in the deathream. This state, known as the "Waking Dream" allows the paragon to access the skill, experience and knowledge of their past lives, as well as the mysterious powers of the dream. Whenever such Paragons are forced to be born, they become the leaders of the tribe. The forceful creation of the first Paragon was is the impetus of the current rise of the Cicada Tide and as such much is still unknown, including how moulting will affect the Waking Dream state, though it seems depressingly likely that it will break the waking dream.
Without a paragon, generally council of children will be chosen from the first instar of the tribe to rule, generally by selecting those that managed to build the best traps in a competition.
General starting biome: A forest with giant trees that have sweet, syrupy sap.
The Cicada are good climbers who prefer to make their homes in large trees. When such are absent, they will probably dig out subterranean buildings in soft soil, or if such is also lacking, build crude structures on the surface.
They are omnivorous, but prefer to subsist on a diet of meat and treesap. Honey may or may not become popular once discovered.
The adult imago subsist entirely on treesap for the rest of their lifespan, though that can easily kill most wild animals with their impressive physical capabilities.
