Worldheart

Worldheart is the core of Apostae, where artificial intelligences keep it running and inhabitable, make decisions that keep it orbiting around the sun, and plan to eventually fulfill its primary mission if the worldship retains its ability to leave Golarion's solar system.

None of this is known to the Ilee native to the world. Great blast doors guarded by laser turrets cover all sides of Worldheart, and Ilee warriors protect the sacred doors from any assault. While none of them understands Worldheart, Ilee legends remind them that it is the key to everything on Apostae.

Most Ilee tribes believe in the prophecy of a Chosen One, who will one day open the way to the Worldheart, past its guardians, take control of Apostae, guide it to a safe, abundant place, and open the surface doors to give the Ilee a new life.
