Cassandra: Fire

The greatness of a civilization lies not only in whether it can conquer the stars, but more importantly in what values ​​it is willing to sacrifice for and turn them into fire to pass on to unknown successors. The universe never promises meaning. Stars come and go, laws are cold, existence itself. Or accidental ripples, or inevitable dust. When a civilization discovers that the physical foundation on which it relies is about to collapse, what comes at the speed of light is not destruction, but a complete "rewrite" - when survival itself becomes a paradox, what is greatness? Conquering the stars is just a footnote to power. True greatness lies in choosing what value to die for. What Cassandra civilization faces is not an enemy, but the inherent voidness of the universe. They failed to surpass the speed of light, but chose to use their own existence to define an eternity beyond physics: turning the entire civilization into a "firewall" to protect unknown latecomers. This book is about how a civilization, in the face of the absolute end, turns its own demise into the most profound answer to the meaning of life - the fire is immortal not because it burns forever, but because it is willing to burn itself out for others.
