Earth Sprites (Story of Seasons: Pioneers of Olive Town)

As you continue to develop your ranch, you'll come across strange little creatures known as "Earth Sprites". They live in the Earth Sprite Village, and if you become friends with them, they may offer you rare crops and materials from their village. At first, they are few and far between, but as you continue to progress, you will find many Earth Sprites. Perhaps they may even bring you to a special place...?

Shrine Blessings
You can receive blessings at the shrine after reaching 100 Follower Sprites and see the third event with Spirit. Once unlocked you can turn in sprite points for blessings that will improve your farm life.

Trivia

 * Earth Sprites speak with an added inflection at the end of their sentences. In Japanese, their sentences end with ん ('n, or "on" like "pon"). This is known as a "gobi" (語尾).
