The visible cracks in a decrepit foundation of stone were exhibited as another part of it was either applied or replaced. The withered stone that was bleached, cracked and infested with mold though bound together was fragile and able to crumble at the most delicate touch. That was one of the varied reasons that the crippling structure was being rebuilt at a haste filled pace.
The humanoid/bird amalgam race known as the Chozo were naturalist and were striving from their temperament to rebuild. They were scientist studying the mass regions of Tallon V. They though able to fly were unable to leave the planet; the reason was that there was an atmospheric layer of poison infested gas keeping the Chozo stranded.
The temple complex the "Adjure" was built from stone, wood and dirt by a group of high priest, known as the "Alcho" which were non-sentient but also weren't artificial builders. The Adjure became a natural wonder that was composed completely of organic materials. Its main purpose was to act as a beacon and/or monument but instead was currently being used for another purpose.
Xenon the Chozo "Clairvoyant" or "Prophet" foretold the Chozo's means of escape by reconstruction the Adjure. "The ruins of the living and dead, lye in the jungle were the living come for nourishment and the dead comes for peace. There in the cathedral lye or dreams and fears." Those words were spoken in an aloof, dry and devoid of emotion sound from the young prophet.
Adjure's purpose was to absorb mostly all of the poison and spread it over the planet while the Chozo escaped the planet. If Adjure was ever to be fractured or detained form its environment to long it would release and anti toxin which would spread the toxin but also weaken it.
The main quandary was to finish before the "Trespasser" which were space pirates would attempt to destroy Adjure. They failed and was forced to retreat from the "cradle" another temple but incompletely finished. The pirates would eventually come for revenge to attack causing the destruction of the cradle.
Also there was the Nosferatu a race of human/bat creatures that feed of the poison. The creatures were somewhat primitive but had enough intellect to know what would happen if the Chozo went through with there plan. The poison though food was manipulative and if the poison spread even further the world would be exposed to the poison killing it faster. The Nosferatu didn't agree with either side but would remain natural.
It didn't matter much because the Chozo were almost complete and settled their dilemma of how to get of the planet. The steps just had to be properly executed. Adjure would be built but its building wasn't urgent as securing the ciphers from the Space pirates.
