These are all conclusions drawn from quest text in the database
- note, this was compiled in about 20 miuntes, very likely I missed extra quests here and there so take what you will from this
You likely retrieve the blade from The Forge of Souls (first 5 man instance). Upon finding the hilt you seek out the aid of other figures your respective faction Silver Covenant (Alliance) or Sunreavers (Horde) who send you to Krasus) at Wyrmrest Temple and discover the blade is Quel'Delar.
Interestingly there are some quests about spying and sneaking into the Silver Enclave in Dalaran to steal an item.
Then you go to Quel'Delar's Rest outside the Coliseum to meet Myralion Sunblaze (Horde) or Caladis Brightspear (Alliance), who send you to the Pit of Saron to reforge the sword. After reforging the sword you discover it is possessed by the Lich King, and wills you to the Halls of Reflection.
[Speculation] Within the Halls of Reflection you will encounter the spirit of Uther [/Speculation] who tells you that "will not always be able to control the blade while it is subject to the evil of the Lich King's influence" And you are sent to the Sunwell to cleanse the blade.
Upon arriving at the Sunwell, you are sent to find the remains of Thalorienn Dawnseeker, to seek his blessing in cleansing and claiming ownership of the sword. You are granted this and enter the Sunwell and cleanse the sword. Some figureheads such as Lor'themar Theron, the regent of Quel'Thalas, and Grand Magister Rommath, will attempt to distract you from this task it seems. The Horde version returns it to the Sunreavers, the Alliance version seems to return it to the Argent Crusade.
