In the old days of heroes and glory, there was a great druid named Kuwusa, who was, in his time, as well known as the mighty Golden Pinions Youhei. He was the keeper of a grove of ancient and mighty oaks in the center of the Forest of Sadjak-To. Many of these trees were magical, and Kuwusa grew many enchanted items upon these trees. One of these items was the Acorn of the Honorable Whiskered Emmisary.
The Acorn is a large acorn, black with an iridescent sheen. It is hung by the stem upon a small chain of silver. It has changed hands many, many times since the death of Kuwusa, and is currently owned by a Voolazi merchant named Pogu Umbasai.
When worn around the neck, the Acorn of the Honorable Whiskered Emissary allows one to communicate with and charm rodents. The bearer of the Acorn can make his spirit leave his body to ride a rodent, seeing what it sees and learning anything that it learns. Over time, rodents will be drawn to the wearer of Acorn, and the wearer will in turn find itself drawn to rodents.
