Kagrenac's Tools are the legendary artifacts crafted by the Dwemer Tonal Architect Lord Kagrenac. Each tool served a specific purpose to siphon the power of the Heart of Lorkhan, via tonal manipulation of the laws of nature.
Kahvozein's Fang is a Dragon Priest dagger that dates back to the Merethic Era. It is legendary throughout Skyrim and is known to be sharp enough to make precise carvings from the scales of a Dragon. It was created by a particular sect of the Dragon Cult, one that worshipped the eponymous Kahvozein. They were very fond of ritual sacrifices, so much so that the high priest spent much time sharpening this dagger so that it was always ready for its next victim.

Keystones are magical stones of significant power associated with the Ayleids. They are primarily found in the ruins of the Barsaebic Ayleids in Black Marsh. The keystones were created in the Merethic Era using the magic of the ancient Argonians, which the Ayleid slavemasters infused in the stones through torment and fear. As such, the keystones exert power over the Hist. There were also used in powerful Ayleid enchantments, such as magical barriers.
Modern research of the keystones is limited by the dangerous nature of the relics. Only certain individuals can handle the keystones without suffering from nervous breakdowns. The Kothringi in particular could handle them for any length of time.
King Orgnum's Coffer
King Orgnum's Coffer is a legendary magical chest, small and ordinary-looking but almost weightless, once owned by King Orgnum of Pyandonea. Once per day a random number of gold coins appear within the Coffer, though in Orgnum's possession it was an unlimited supply.
King Orgnum lost his Coffer at sea, in a battle against Emperor Antiochus Septim during the War of the Isle. With the loss of this source of endless wealth, Orgnum could not afford a fleet as great as he had had, leading to Pyandonea losing its status as a world power. It is said that when found the Coffer always disappears again, but not before producing enormous wealth for its owner. Where and why it vanishes is a mystery. It was last seen in the hands of the Eternal Champion.
