Speak with Justicar Mariel Trueheart at the Argent Tournament Grounds.
You have earned my respect and the respect of your peers. You defeated all who challenged you and mastered the ways of tournament combat. I have no doubt that you are ready to face down the champions of other cities for the glory of the Darkspear!
Justicar Mariel Trueheart has asked to speak with you, <name>, and to formally enter you in the champions' grand melee.
I welcome you as a champion of the tournament, <name>. As a champion, you will be able to compete for the grand championship of the tournament. You may also choose to become a valiant with another Horde city's delegation and in time, a champion for that city as well.
All champions must have the assistance of a squire, <name>, and you are no exception. Allow me to appoint one of ours to accompany you in battle. He will proudly carry the banner of any city that has named you a champion.
