- Epilogue of The Persistence Canon: Origins

 is a unique Akaviri Katana originally used by the Dragonguard in the first Era and later discovered by Breton Princess and Dragonborn, Alyssa Lariat. It was the blade that dealt the finishing blow to Alduin, the world-eater.

Appearance
Dragonsbane is an Akaviri Katana, the sword that the Blades used during their service to the Septim Empire. The hilt is wrapped in strips of black leather and the guard is Dragonbone in the shape of coiled dragonbones. The weapon's enchantment, damage to dragons, causes a visual effect where sparks of electricity fizzle along the length of the blade.

History
Historically this blade belonged to the Dragonguard and was left in Sky Haven Temple, where it layed dormant from the first era until the fourth when the Last Dragonborn, Alyssa Lariat, rediscovered it together with the Dragonslayers, aided by the Blades. She kept the blade with her and used it throughout the Dragon Crisis, it was the blade that dealt the finishing blow to Alduin at the whalebone bridge in Sovngarde, at the end of the Dragon Crisis, she left it at the peak of the Throat of the World, stabbed into the rock with the Amulet of Talos bound around it's hilt. Standing as a symbol of Hope for the Mortals of Tamriel, for evermore.

Acquisition
It was originally obtained in Sky Haven Temple by The Last Dragonborn. Located on a table in an atrium just off to the left of the main chamber, along with a full set of Blades armour.

Enchantment
Dragonsbane's unique enchantment causes an amount of extra damage to dragons and Shock Damage to others; this is not the same as other shock damage enchantments, however, since it does not do any Magicka damage. After it was used to defeat Alduin and Alyss spoke the words "Alduin Mahlaan" the sword was affected and gained a third ability becoming even more deadly to all dragons.

Smithing
Dragonbane can be upgraded by use of Dragonbone and Steel Ingots and the Arcane Blacksmith perk at a grindstone, and also benefits from the Dragon Smithing perk, which doubles the improvement.
