Two years later, Aleron and Tern had settled just inside the city ruins in the Forbidden Zone, and there organised a rag-tag community of humans who planned to assert their rights. Prisca, by then working on human research with Servicus, was under suspicion when the humans began to raid ape villages, and with the help of Doctor Milo made her way to Aleron's camp. The sympathetic chimp Timon eventually betrayed Aleron to Doctor Zaius and guided an ape army to the secret lair. Zaius' army wiped out most of the humans, with Tern and his family escaping on rafts, but Aleron died destroying the passageway that led to the Forbidden Zone, trapping Timon inside for many years.
