The Vampiric Ring is one of the more deadly and rare artifacts in Tamriel. It is said to have the power to steal its victim's health and grant it to the wearer. Its exact nature and origin is wholly unknown, but it's thought to have been created long ago in Morrowind by a cult of vampire followers. It is extremely rare, and is only seen every few hundred cycles of the moons.
Veloth's Judgement (also called the Judgment of Saint Veloth) is the magical Daedric warhammer Saint Veloth wielded during his exodus from Summerset. This symbol of power stood for everything Veloth embodied. Veloth's Judgment was said to have rang with authority throughout the land. Its enchantments could cleanse corruption from the souls of those it struck down.
Veloth's precision with the hammer was such that he could remove the corruption from a soul and leaving the remainder alive and healthy. The warhammer stored the corruption for a time, turning it into energy that could be used by the wielder to enhance the power of the weapon. Veloth saw fit to set aside this weapon when he vowed to turn his attention from war to the task of building a new home for the Chimer in Resdayn.
Volendrung, also known as the Hammer of Might, is an ancient artifact created by the Dwarven Rourken clan. In appearance, it is a large ebony warhammer, although it may sometimes take the shape of a blade. For unknown reasons, Volendrung became a Daedric artifact of Malacath. It earns its name with its capability to demolish the walls of enemy keeps with ease. It is enchanted with the power to paralyze foes and drain them of their strength, conferring it to the wielder. The hammer is prone to disappearing like its Dwarven creators, sometimes resurfacing in days, sometimes in eons.
The hammer originally belonged to the chieftain of the Rourken clan. When his clan refused to join the other Dwemer in the First Council, the chieftain threw his hammer across Tamriel, promising to settle where ever it landed. The hammer landed in western Tamriel, and the Rourken called the land Volenfell, literally "City of the Hammer". This area later came to be called Hammerfell. The Rourken's journey across Tamriel is depicted in many of the ruins of the region, Volendrung appearing as a shining star showing the way.
