The vodyanoi are intelligent underwater dwellers. Vodyanoi warriors are the stronger variety who protect other, weaker vodyanoi, like the priests. They may well be the same creatures as the "warriors of Ys" described in the short story "Trochę poświęcenia" ("A Little Sacrifice") in the Miecz przeznaczenia (The Sword of Destiny) collection by Andrzej Sapkowski. see also: Vodyanoi priests
