Overview: Deathwater Island is the island where a pool turns anything into gold, tempting Caspian toward greed and violence.
Place in the books
Deathwater Island matters because it lets Lewis dramatize avarice with unnerving clarity. Gold here is not reward. It is danger. The island reveals how quickly wealth can corrode loyalty and judgment.
It is also one of the best reminders that not every marvel in the east is a blessing. Some wonders are tests.
