Imperium Nihilus: Vigilus Defiant (2018), p36 — Hope Yet

Since the fall of the Oteck Hollows, water was becoming ever scarcer upon Vigilus, and the convoys for its transference less and less common. With Grodholev Subsprawl falling to the Gellerpox, Dontoria was in danger of losing its own main source of water - Lake Dontor, which was now under daily vigil in case of disease. The Vigilus Senate had still not located the Death Guard forces that had brought the Gellerpox to the planet, and suspected that if the traitors found a way through the firewall they would move against the lake with yet more contaminants.
