On the purpose of the Argent Tournament itself, Highlord Tirion Fordring makes the following announcement from the stage to the east of the Ring of Champions at the top of every hour:
Five minutes before Tirion speaks:
Herald Beluus yells: Highlord Tirion Fordring approaches the stage to address those gathered upon the tournament grounds! Make way to the stage area to attend him!
Combatants of the Alliance and Horde! You are welcome under the banner of the Argent Crusade.
To the south lies our goal. We will march to the Citadel and cut out the heart of the Scourge where it dwells.
But this is no task to be taken lightly.
A massive attack with every able-bodied man would end in needless slaughter. Every soldier lost would rise as the enemy. Azeroth would be left defenseless against the undead threat.
Instead, we require a small, concentrated strike force for the attack to succeed. For that reason, we have created the Argent Tournament.
Within these walls, you will be tested. Your skill in combat will be matched against the fiercest dangers Northrend has to offer under the watchful eyes of your leaders.
Your prowess, your might, and your cunning will be under close watch. These games will determine the best Azeroth has to offer.
The victors will take their rightful place in the assault upon the Citadel. We will stand together in the face of evil, and Arthas WILL fall!
Starting the Argent Tournament: Aspirant & Valiant
The quest chain starts in the building to the west of the Crusaders' Coliseum. Justicar Mariel Trueheart directs questers to their faction's respective tents on the east side of the keep, where they must undertake a series of tests to join the tournament proper.
After completing "The Valiant's Challenge", the following quests open up allowing players to repeat the valiant stage of daily quests (steps six and seven) for the other factions with which they have not yet earned the right to champion:
After completing "The Valiant's Challenge", the following quests open up allowing players to repeat the valiant stage of daily quests (steps six and seven) for the other factions with which they have not yet earned the right to champion:
Also note that like the fishing and cooking daily quests, the 3 blade quests (A Blade Fit of a Champion, The Edge of Winter, A Worthy Weapon) are not independent daily quests. Having one of them in your log prevents you from accepting the other two, should it be offered that day. In other words, should you not complete one of them on the day you accept it, you will not be able to do either of the other two quests the following day. This means that you should do all three daily quests on the day you accept them if you want to complete "Up To The Challenge" in three days.
Completing the four available valiant dailies will reward 52 92 and 5x[Valiant's Seal] each day.
Over the course of championing all five faction's cities you can expect to gain 11,250 reputation with each capital city. Keep this in mind when considering champion-level quest rewards. The [Champion's Writ] can only be used to buy reputation tokens worth 250 reputation with one city at a time. Do not purchase reputation with a faction when you can reasonably expect to reach exalted status while doing the valiant chain for the rest of the cities. The [Champion's Purse] is a better alternative for players who already have high reputation with their faction's cities. It is also possible to continue doing a faction's valiant-level quests, earning reputation with that faction, if one does not turn in the "The Valiant's Charge" quest with that faction.
Completing all Champion, Sunreaver/Silver Covenant and Crusader dailies will reward 159 07 total, including 10x[Champion's Seal].
Crusader dailies
In order to be eligible for these quests, players are required to have earned the title <Crusader>. Several daily quests are offered randomly each day, one from each questgiver:
Earn exalted status with and the right to represent every Alliance race's faction in the Argent Tournament while also being exalted with the Argent Crusade.
Earn exalted status with and the right to represent every Horde race's faction in the Argent Tournament while also being exalted with the Argent Crusade.
Herald Beluus yells: The Warchief of the Horde, Thrall, and Overlord Garrosh Hellscream have arrived upon the tournament grounds! Clear the way to the entrance!
Thrall says: Thank you for the invitation, Lord Fordring. We look forward to observing these games.
Garrosh Hellscream says: Speak for yourself, Thrall.
Highlord Tirion Fordring says: I hope you'll see the merit of these events in time, Garrosh. We cannot win against the Scourge if we continue to war against one another.
Thrall says: Wise words.
Garrosh Hellscream says: Words of a fool, you mean. The Horde will destroy the undead without your aid, human, or that of the pompous king.
Thrall immediately turns to face Garrosh and rebukes him directly.
Thrall says: Garrosh, enough!
Highlord Tirion Fordring says: Under my roof, gentlemen, I trust you will behave.
Thrall turns back to Tirion.
Thrall says: Of course, Tirion. I apologize for his outburst. It will not be repeated.
Garrosh Hellscream says: Bah.
Highlord Tirion Fordring says: If you will follow me, then.
The group then walks in to the coliseum proper and disappears inside.
Herald Beluus yells: His Majesty, King Varian Wrynn, and Lady Jaina Proudmoore have touched down upon the tournament grounds! Make way!
Varian, Jaina and their escort appear from inside the Silver Covenant Pavilion and walk west towards the Argent Pavilion. Fordring greets them at the entrance to the Coliseum.
King Varian Wrynn says: Tirion.
Highlord Tirion Fordring says: King Varian, Lady Jaina. Welcome to the tournament. Your place in the coliseum is waiting.
Lady Jaina Proudmoore says: Thank you. It's the least I can do to support this; we need to stand together.
King Varian Wrynn says: You ask much of me, Tirion, to sit and watch, trusting the savages to keep themselves in check.
Highlord Tirion Fordring says: My people are here to ensure they honor the rules of engagement. It will do your subjects well to see you in the stands.
Lady Jaina Proudmoore says: I'm sure Thrall will have his people under control...
King Varian Wrynn says: Perhaps. I doubt the effectiveness of this gambit. We would be better served preparing our armies for the final assault.
King Varian Wrynn says: But if my presence is required in these games to gain your support in the battle, then I will remain. For now.
Highlord Tirion Fordring nods and gestures for his guests to follow.
The group then walks in to the coliseum proper and disappears inside.

Just when you thought you had seen the last of the Black Knight, he makes his astonishing return to the tournament. Wait, didn't you kill him? (Source)
