Deathwater Island

Deathwater Island (briefly called Goldwater Island) was one of the numerous islands visited by Caspian X and his crew during his voyage aboard the Dawn Treader. This island was home to a magical pool that would turn anything and anyone that touched it into pure gold. Caspian, possessed by the thought of inexhaustible riches, called the island "Goldwater", and prepared to draw his sword on Edmund when the latter attempted to contest his authority as King. The brief vision of a Lion that appeared on the hilltop above them immediately made them realise the foolishness of their actions. All memory of the incident was then lost to the group. Reepicheep the mouse, by means of an unknown inspiration, suggested the name of "Deathwater" instead, and Caspian obliged.

At the bottom of the pool, there lay a statue made of pure gold. The arms and armour that Caspian's group found lying about the pool made them realise that the statue was none other than Lord Restimar, who presumably had wanted to take a bath on a hot day, years before, and had accidentally turned himself into gold.
