Not to be confused with Waters at War. That is completely different.
War Water is "food" given to Water Dwellers who served in World War III, during its years in Australia (2013 - 2018). It was mostly untreated, leaving it impure, yet safe to drink. War Water causes rapid weight loss in long-term drinkers, as it contains more chemicals/organisms than clean water. The most famous example of its effects is that of Holly Axolotl, a Water Dweller whom had once lived on Clearwater Mountain, where the water is pure. After her body became addicted to water, drinking Clearwater Water barely affected her. She lived there for nearly a year and lost very little of her starting weight. It was only when she reached the warzone, and was given War Water that she lost her weight.
