Peaceful and pretty creatures live in a picturesque green valley. They are peaceable, but not stupid, so they always keep gunpowder dry. The reason for their fear is that in the center of the valley is a large altar, which they worship. It is a round table over which multi-colored precious crystals soar. It is they who can attract jewelry hunters. Soon it happened. An army of monsters has appeared on the border of the land and is already about to attack. You will help the creatures defend themselves and for this in Keeper of the Groove you need to place warriors along the main road leading to the altar.
