From the mud and desolation of the primitive wasteland, the faint soul fire that was almost extinguished struggled to light up. After a hundred years of tempering and fighting, it finally became the Bone Palace covering the entire mother planet. Each bone brick is engraved with the struggle and glory of the skeleton clan.
Using broken bones as the cornerstone and unyielding soul fire as firewood, they forged a civilization unique to skeletons in the cracks of nothingness; using scientific research as the blade and trial and error as the path, they forcibly penetrated the growth cage of their home planet. Amidst the ashes of countless failures and hundreds of years of desperate struggle, they finally opened the phase door to the endless heavens, letting the unknown light shine into the dead planet.
For the skeleton tribe, without growth, the soul fire will eventually dim and dissipate; without boundaries, the journey will never stop. This is the iron law of survival engraved in the soul core, and it is also the light of faith that supports them in overcoming desperate situations.
