A long-long time ago and far-far away in the Underground Kingdom there lived a small prankish demon. He led usual devilishly unattractive life - polishing cauldrons, keeping fire alive, sweating with the infernal heat. Once it happened that the senior demon found fault with demon’s work. And he sent delinquent demon to the Devil. The Devil then said: “You’re guilty, demonic one... It’s time to redeem your fault… Set out for the Earth and find there three unaccounted souls, which are hiding in the cloister!” The demon had nothing to do but to obey his devilish master. He appeared on the monastery court in flames and clouds of smoke and proceeded to carry out the hard task. Monks are not eager to help the demon. Moreover, they are making signs of the cross over him and trying to drive the demon back to Hell. But he can’t return without the souls! For accomplishing his mission our imp has to solve awfully tangled puzzles and moreover not to come across opposition of silly and deceitful priests and other inhabitants of a huge medieval Monastery as they always try to stir him. But burning devilish humor helps our funny fellow to cope with any difficulties!
