Ch. 362A vague unease
Petru investigated the Tapu on the South Pacific islands and discovered that their stones carried powerful mental energy, linking them in his mind to the mummy, the charts, and the people pursuing him. He settled on Tubuai Island, where his mental power grew and he found that weapons kept in the Tapu seemed to help him aim at distant targets.
- Petru reasoned that the Tapu were likely connected to the pirate who drew the charts, rather than being ancient Māori altars, and suspected the surrounding islands hid clues to a secret.
- Petru entered a Tapu near the Bass Islands and endured a mental assault that could drive ordinary people mad; he adapted and sensed the stones held ancient mental power.
- Petru connected the Tapu to the mummy, the charts, and the powerful mental practitioner who had escorted the freighter, and concluded that the ship had been bound for a Ghost Island or the surrounding triangle.
- Petru moved to Tubuai Island, settled near its Tapu, laid traps, and used force and generosity to persuade the islanders to leave him alone.
- Petru explored nearby islands and trained in the Tapu, where his mental power grew despite his lack of guidance.
- Petru discovered that guns and bullets kept inside the Tapu seemed to acquire faint mental energy, helping him aim at distant targets without a scope.
