Lore:Ring of Surroundings
The Ring of Surroundings is very mysterious. Almost all that is known about it is that it grants the user the ability to blend into its surroundings. 
The Nerevarine reportedly found the ring on Vvardenfell in 3E 427, though reports on its acquisition conflict. Some say that the Imperial Legion rewarded the ring to the Nerevarine for wiping out the Camonna Tong's presence in Balmora. Others state that the Camonna Tong's kingpin, Orvas Dren, had the ring as part of his collection in his residence. These reports may not even conflict, as some even believe that there is two Rings of Surroundings in existance.
