The Antalu Planet is not the only planet with life in this star system. To be precise, the Third Planet is the most thriving planet for life, the true chosen star, while Antalu is merely a poor and remote area receiving a minimal amount of stellar radiation.
Perhaps it is because adversity breeds strange things, originating from the Fourth Planet, the "Sakali" used all their strength to resist the life-reaping of the mysterious red cloud. In a life-and-death struggle, they miraculously turned the tables on their opponent, reversing the roles of hunter and prey.
The bizarre scarlet cloud was swallowed by the miracle child of "Sakali," preventing the civilization from its ultimate fate of being harvested, allowing the entire race to survive.
Perhaps it was because of the reversal of fortune that the "Sakali," who won this survival battle, experienced a leap-like group evolution comparable to that from ancient apes to Homo Sapiens in a short period of time.
