A STORY THAT CONTINUES.DISCOVER →
Nav
The world of the dead, where memory and time obey different laws. Not everyone returns — nor always as they were.
Prav
The law that maintains the boundary between worlds. Koschei keeps the living among the living and the dead among the dead.
What lies behind this story
Folklore as part of the world
Slavic imagery is more than decoration here. Deities, spirits, rituals and beliefs define the laws of the world and shape the fates of its heroes.
Nav is more than a world of the dead
It tests people through memory, loss and fear. Sometimes the most dangerous thing in Nav is not a monster, but what a hero is willing to forget.
Koschei is not a villain
Koschei is the guardian of Nav. His immortality is not a gift, but the price of keeping the living and the dead on opposite sides.
Original universe
The series, music, characters, lore and visual world are created as a unified whole.
An anthology in one universe
Koschei opens the world of Shadows of Nav. Each new story may reveal another era, another hero or an ancient secret of this universe.
