The original Russian-language version of the Mirror World series by one of the founding fathers of LitRPG!
Mirror World is stirring, about to embrace the new global changes of its map. Everyone is getting ready to colonize No-Man's Lands. The strongest clans send their best fighters on recon missions, impatient to make a stake for the juiciest locations.
Market prices have taken to the sky like flocks of scared pigeons. New alliances are struck while mercenaries upgrade their armor and grind an edge on their swords. Their time is looming.
A war is coming to Mirror World.
Olgerd too is getting ready, a new goal already in his sights. The ancient Ennan City awaits him.
All he needs to do now is gain some strength.
