The Ring of Winter was a powerful magical ring with numerous magical capabilities.[2]


The ring was a golden featureless band that was constantly covered in a layer of frost that never melted. It was extremely cold to the touch and could numb the hand of its wearer. It did not seem cold to someone who had been attuned to it, however.[2]


The ring made it impossible for the wearer to be detected through divination magic, rendered its wearer immune to cold, and halted aging entirely. It also constantly attempted to take control of its wearer to compel them to cause unnecessary harm and destruction.[2] Artus Cimber however, upon acquiring the ring, believed this to be a continuous test by the ring. Cimber believed the ring to ultimately have a purpose of good, and that the ring therefore wouldn't allow corruptible people to wear it.[3]

The ring was capable of quickly and permanently lowering the temperature of a 120‑foot (37‑meter) radius sphere to a minimum of −30  (−34 ), and could do this multiple times until the wearer decided to end the effect. It could create inanimate objects and animated creatures made of ice. It was also capable of casting the spells Bigby's hand, cone of cold, an icy variant of flesh to stone, ice storm, Otiluke's freezing sphere, sleet storm, spike growth, and wall of ice. The energy spent by the ring to do any of these effects was regained daily at dawn.[2] Cimber used the ring's ability to create inanimate objects, manifesting rapiers of ice.[4]


Before 1362 DR, the ring had been hidden within the Temple of Ubtao in the lost city of Mezro, hidden there by the bara, Dhalmass Rayburton of Cormyr, after he had used the ring and thereby accidentally murdered several people. The former Harper, Artus Cimber, after spending years of his life searching for the ring, learned of the location of the ring and retrieved it, thereafter using it to repel a goblin invasion of Mezro.[3]

At some point after the War of the Silver Marches of 1485 DR, the ring was relentlessly sought after by the frost giant, Jarl Storvald, as he believed it to be a way to raise frost giants in the ordning. The Zhentarim were also looking for the ring around the same time, and Nilraun Dhaerlost informed Jarl Storvald that the ring was in the possession of Artus Cimber. The frost giants used a blod stone to locate Artus Cimber through his blood, but were instead drawn to his son Sirac in Bryn Shander. The leader of the raiding party, Drufi, then attacked the city with twelve frost giants following this incorrect lead, but their attack was thwarted by the city's inhabitants, with the help of adventurers.[5]

After their failed attack on Bryn Shander, Drufi and her fellow giants journeyed to the jungles of Chult to search for Artus Cimber there, causing much confusion among the local rulers.[6]

Around the same time, the half-elven sorceress Xandala journeyed to Port Nyanzaru in search of Cimber, seeking to wrest the ring from him. To this end, Xandala attempted to manipulate a party of adventurers by claiming to be Cimber's lost daughter.[7]


It was said that the ring had other powers that could only be accessed by an evil being who did not fall under control of the ring. It was rumored that the ring could be used to summon white dragons, or the primordial Cryonax, and freeze entire worlds.[2]

It was said that the ring could only be destroyed if worn by the Summer Queen.[2]
