Polanie II, also known as KnightShift and Once Upon a Knight, is a real-time strategy and role-playing video game hybrid developed by Reality Pump Studios and released by Topware Interactive for the PC Windows and OS X in 2003.

The main character of the campaigns is Mirko, prince of Polans from the first game (in Knightshift, his name was changed to John).

In the intro cinematic, evil wizard Koschei (in English - Valtamand) sends him to the interdimensional void between life and death, and causes him to lose his memory.

After five years pass, with help of the Slavic gods, sage Dobromir (in English - Gallus) managed to bring Prince back from the void, and sends him on a quest to restore his princedom.

Mirko is forced to slay him, and Mieszko in dying words reveals he unwittingly allowed Koshchei to send the prince away all these years ago.

Prince heads on alone, but the fight slowed him down, allowing the dark wizard to grab the final Jewel, tauning Mirko in his face before teleporting away.

The final last ditch attempt is to use a Dragon Sword to destroy the Jewels in an all-out assault on Koschei's fortress.

In a final, comical cutscene, Koshchei accidentally casts a spell on himself, and flies away in a puff of smoke.
