Sezom falls dying after saving Romana

Sezom collapses after dragging Romana to safety from the Nimons, his body failing from years of self-imposed starvation and guilt. As Romana tends to him, he confesses his complicity in the Nimons' arrival, revealing he worked their tribute system and doomed Crinoth for imagined power. His final breaths buy Romana time to grasp the full scale of the threat before he dies, leaving her with the knowledge and urgency to escape and warn Skonnos before the planet collapses. key_dialogue: [ SEZOM: I am Sezom. ROMANA: You just saved my life. Are they dead? SEZOM: Alas, no, but they will be unconscious for a while. Who are you? Why are you here? ROMANA: I'm Romana. I'm here by accident. Where are we? SEZOM: This is Crinoth, what's left of it. SEZOM: My time is almost up. ROMANA: Here, sit down. SEZOM: Thank you. ROMANA: There, how's that? SEZOM: Better. You're very kind. ROMANA: You did just save my life. SEZOM: But I have caused the deaths of so many others. The total destruction of our planet and all its people. I am to blame. ROMANA: Why? What did you do? SEZOM: I allowed the Nimons to come here. I worked for them, became their creature. They promised us technology, peace, prosperity. SEZOM: There was only one of them to start with. I never knew what was to come. I swear, I never knew what was to come. It seemed such a small price to pay. ROMANA: It always does. ]
