Dawnbreaker (Skyrim)

The Dawnbreaker is a Daedric artifact given by Meridia. It can be obtained during the quest The Break of Dawn that you can start by visiting the Statue to Meridia. Once started, Meridia will ask you to become her champion and restore her influence over Skyrim by restoring her temple, which has been hijacked by a necromancer. She commands you to first find her beacon that is seemingly spawned into different locations for different people. Upon obtaining the beacon, Meridia speaks to the player, commanding you to take the stone to her shrine, which is located west of Solitude, almost directly south of Wolfskull Cave. Once there, Meridia will tell the player that there is a powerful necromancer defiling her temple, which the player must navigate through and kill.

Alternatively if you obtain the beacon before visiting Meridia's shrine and place the beacon in your inventory, Meridia will speak to you commanding that you return it to her shrine.

When near enemies or ancient nord ruins the sword exhibits a bright glow. This weapon also has a very high number of charges, much higher than most other enchanted weapons. Since soul gems restore a percentage of charges, this weapon provides a lot more uses per soul gem than most other weapons.

Bugs

 * There is a glitch where you can receive two copies of the Dawnbreaker sword. When entering the chamber to fight the necromancer, cast a powerful Firestorm scroll. A Blizzard scroll works just as well. This will cause a copy of Dawnbreaker to go flying across the room, while the original still stays where it is. Pick up the copy before obtaining the original because this ends the quest. The best way to do this is to cast the spell after you have defeated the necromancer and his shades. Stand in front of the altar and cast the spell, the sword should be somewhere on the ground. (Confirmed XBOX360, PS3 and PC)
 * This weapon seems to be able to accidentally equip itself to the same hand as another weapon at the same time. This may be due to using the item duplication glitch above.
 * The in-game description of the weapon's effect contains a spelling error, describing the damage bonus as a "firey" explosion. The correct spelling of this word is "fiery."
 * If equipped with a weapon of a different kind in the left hand, Dawnbreaker may take the form of the weapon in the left. Confirmed with Daedric Long Sword. To fix simply un-equip and then re-equip Dawnbreaker, the weapon should now be displayed properly.
