The Wandering impling is a special NPC located in the wheat field in Zanaris. When talked to, he will show the location of the random Crop circle to Puro-Puro. He will not tell the name of the location, but a short cutscene will play to show it. This can be useful for players in Zanaris as it is an easy way to find the crop circles and get the 30 minute farmer's affinity bonus, that allows players to push through the wheat faster (as of 22 February 2010), the player can communicate the location to others who don't have access to Zanaris. The Wandering impling looks similar to an Essence impling, but with red robes instead of blue.
