Spell Breaker (Oblivion)

Spell Breaker is a powerful shield said to have been created by King Rouken, one of the last Dwemer kings, to aid him in his battles against the wizard Shalidor. Spell Breaker is a heavy armor shield which provides 30% spell reflection. This shield is in the pattern of an ancient Dwemer shield and can be obtained through the Shrine of Peryite.

History
During the Oblivion Crisis, the Taskmaster asked the Champion of Cyrodiil to rescue the trapped souls of his followers. They were trying to reach the realm of Peryite, but instead their souls were transported to another realm, most likely Mehrunes Dagon's as it was time when Mehrunes Dagon launched his attack on Tamriel with many small fiery realms as bases. The Champion of Cyrodiil was eventually successful and managed to rescue all of the trapped souls and return them to their body. Peryite rewarded the Champion with the Dwarven shield: Spell Breaker. Detail conversation of the event can be read here.

The shield was also rewarded by Peryite to the Hero of Daggerfall decades earlier after completing a different contract for the Daedric Prince. It is unknown as to how Peryite managed to retrieve the Spellbreaker from each of its owners. The Eternal Champion was also one of the wielders of the Dwarven shield. He found the shield somewhere in Hammerfell- which was perhaps the original place of the shield. The legend says: ''Spell Breaker, superficially a Dwarven tower shield, is one of the most ancient relics of Tamriel. Aside from its historic importance dating from the Battle of Rourken-Shalidor, the Spell Breaker protects its wielder almost completely from any spellcaster, either by dispelling magics or silencing any mage about to cast a spell. It is said that the Spell Breaker still searches for its original owner, and will not remain the property of anyone else for long. For most, possessing Spell Breaker for any time is power enough.''

According to the text above, the tower shield has some connection with the Dwemer clan of Rourken, which was situated in Hammerfell. So it is highly possible for Hammerfell to be the original home of the tower shield, but the connection of Rourken and Peryite, is currently unknown.
