Moonwater is a magical drink used by the Hunters of Artemis. It gives energy and power similar to "six hours of sleep and a good hot meal." Men rarely have a taste. The hunters use this as an energy drink. Even large animals don't need large quantities of moonwater to get energized.
Appearance[]
It looks like regular water with a hint of silver, like it has "trace amounts of mercury."
The Trials of Apollo[]
The Dark Prophecy[]
After escaping Commodus' forces, Thalia Grace offers some moonwater to Apollo and Livia. Apollo then wonders how Artemis kept it a secret from him for so long.
