Dome of Doom: Crimson Age

-Apocalyptic triggers: "The advent of the red tide" in 2147 - unknown particle streams from the M-78 nebula hit the earth. 70% Of humans mutated into "energetics" (surviving by devouring biological energy, with shapes ranging from aberrants to behemoths). The remaining humans hid in 12 "dome cities" and relied on "star nuclear energy" to survive. -Power structure: Dome Alliance (officially led, strict hierarchy), Scavenger Guild (wandering in the ruins, competing for resources), Awakened Mutants (a group of humans who have not completely mutated but gained superpowers, and are hunted by both parties), Energy Phagocytrium (intelligent high-level mutants, planning to destroy the dome). -Core conflicts: competition for resources (exhaustion of star core energy), identity confrontation (humans vs mutants vs awakened ones), truth exploration (red tide is not an accident, there is a conspiracy of interstellar civilization behind it). -Upgrade system: Humans rely on "star core chips" to enhance their physical strength/technology, awakened ones rely on "particle resonance" to unlock elemental/spiritual abilities, and energy-phagic bodies rely on "swallowing evolution" to unlock form transitions. The three form a chain of checks and balances.
