Quote From Out of Cards

PreMission

  • Thrall: Early in my life, I did not know who I truly was… or who my people were.
  • Thrall: Everything around me was defined by others—like my master, the Alliance lord, Blackmoore.
  • Thrall: When he bade me to eat, I ate… to sleep? I slept… And to fight? I fought with all my heart.

Intro

  • Thrall: Yes, master.
  • Blackmoore: Come witness the might of my pet orc!
  • Blackmoore: These people are paying good money, Thrall. I trust you'll put on a show for them?

Exchange

  • Thrall: If I don't keep fighting, Blackmoore won't be pleased…
  • Blackmoore: I trained this orc foundling to become the ultimate warrior!
  • Blackmoore: Would you believe me if I told you he also likes to read?
  • Taretha: Thrall, this is too much for you.
  • Taretha: He is wrong to treat you this way.

Victory

  • Thrall: Yes, master.
  • Thrall: I did my best, and it still was not enough for him. You may be right…
  • Blackmoore: Well, I'm off to celebrate and spend your earnings! Rest up for your next match, Thrall.
  • Taretha: He's gone! This is your chance to escape!

Loss

  • Blackmoore: You owe me everything! And this is how you choose to repay me…

Idle

  • Blackmoore: Some people keep pet dogs or cats, but I prefer orcs. They eat a lot though.
  • Blackmoore: After the Second War, most orcs ended up in camps. However, they make great entertainment!
  • Blackmoore: This orc has been trained to be perfectly obedient. I'm certain he's not faking it. At all.

HeroPower

  • Blackmoore: Bring another challenger!
  • Blackmoore: Let's see how he fares against this one!
  • Blackmoore: Watch him defeat this foe!

EmoteResponse

Quote From Out of Cards

PreMission

  • Thrall: With Taretha's aid, I managed to leave, although she paid dearly for helping me.
  • Thrall: Despite that, I reconnected with my people and discovered my true heritage. I learned I was the son of the late Durotan, leader of the Frostwolf Clan.
  • Thrall: His shaman, Drek'Thar, had survived the wars, and he began teaching me the ways of the elements.

Intro

  • Thrall: I am ready.
  • DrekThar: Prepare to meet the spirits of the natural world.

Exchange

  • Thrall: I… do not know.
  • Thrall: I ask for strength and power against my foes.
  • Thrall: Give swiftness and stamina to me and my allies. Ensure we never tire in battle!
  • Thrall: Burn through my enemies! Never let my courage fail!
  • Thrall: To heal my wounds and replenish my strength.
  • Thrall: Preserve my connection to all living things—a power beyond words.
  • DrekThar: What would you ask of the Spirit of Earth?
  • DrekThar: Knowing is part of the test.
  • DrekThar: It is granted.
  • DrekThar: What would you ask of the Spirit of Air?
  • DrekThar: It is done.
  • DrekThar: What would you ask of the Spirit of Fire?
  • DrekThar: So be it.
  • DrekThar: What would you ask of the Spirit of Water?
  • DrekThar: Very well. One element remains…
  • DrekThar: What would you ask of the greatest of all, the Spirit of the Wilds?

Victory

  • Thrall: I thought I would feel so mighty… but instead, I am humbled.
  • DrekThar: All of the Spirits will aid you.
  • DrekThar: That is what makes you worthy.

Loss

  • DrekThar: What a shame. I had thought you were doing so well.

Idle

  • DrekThar: It requires patience to become a true shaman.
  • DrekThar: The orc shaman are older than the warlocks. Our ways are the ways of the clans before the Horde.
  • DrekThar: Sometimes the spirits will not answer your call, and you must be prepared for that.

EmoteResponse

  • DrekThar: Look to the spirits, not to me.

Quote From Out of Cards

PreMission

  • Thrall: My days with Drek'Thar and the Frostwolf Clan passed peacefully. But I heard tales of an orc warrior who had never been captured—Grommash Hellscream.
  • Thrall: I wanted to join him in liberating the rest of our people. However, a mysterious stranger insisted on opposing me…

Intro

  • Thrall: I was raised by humans! We know things they do not. We must not be bound by fear!
  • Orgrim2: Hellscream is a fool. We have all seen what the humans can do… the bloodshed…

Exchange

  • Thrall: I will not be silent!
  • Thrall: So long as one orc is in danger, we all are!
  • Thrall: Our people must be free!
  • Orgrim2: See if you can take me, whelp!
  • Orgrim2: The Frostwolves are right to hide from the humans, far from the danger.
  • Orgrim2: Why must we suffer so much for so little? For valor? Bah.

Victory

  • Thrall: Second? But… I beat you, stranger.
  • DrekThar: He is no stranger, Thrall.
  • Orgrim2: Long has it been since anyone could challenge me. I have found my second in command!
  • Orgrim2: My name, son of Durotan, is Warchief Orgrim Doomhammer!

Loss

  • Orgrim2: I wonder… was I wrong to come here to meet you?

Idle

  • Orgrim2: You are only just learning your history.
  • Orgrim2: Should the orcs revolt, it will mean another war…
  • Orgrim2: Do not ask me about my own clan… Theirs was a hard fate.

HeroPower

  • Orgrim2: Yes, face my hammer!
  • Orgrim2: Can you stand up to me?
  • Orgrim2: How much fight can you bring?

Quote From Out of Cards

PreMission

  • Thrall: It was a test, and I had passed. Together, the Warchief and I fought to free our people.
  • Thrall: When he fell in battle, he charged me to take up his place—and his hammer. Once the orcs were liberated, we sailed to Kalimdor to begin anew.
  • Thrall: But I realized the orcs had more than one master. With one gone, another came to claim us… the demons.

Intro

  • Thrall: Your hold on him ends now!
  • Mannoroth: I knew you would come, and I see you brought the mighty Hellscream.

Exchange

  • Thrall: It matters not. I helped my people escape from the camps, and I will help them escape from you!
  • Mannoroth: His blood is mine, as is your whole cursed race!
  • Mannoroth: You made the pact willingly, Hellscream.
  • Mannoroth: You chose to drink my blood… to bind yourself to me.
  • Mannoroth: And you, "Warchief"… you were not even there.

Victory

  • Thrall: You have freed yourself, old friend… You've freed us all.

Loss

  • Mannoroth: The Horde has always belonged to ME.

Idle

  • Mannoroth: So much hatred in your heart, Hellscream… we are the same.
  • Mannoroth: I know what burns within your soul.
  • Mannoroth: All of this is futile, as it always has been.

HeroPower

  • Mannoroth: I am the rage in your heart.
  • Mannoroth: Feel the fury of your thoughts.
  • Mannoroth: Stupid, pitiful creatures…

EmoteResponse

  • Mannoroth: Ahahahaha…

Quote From Out of Cards

PreMission

  • Thrall: Our triumph heralded a new era. As Warchief, I kept peace with the Alliance, while listening to the many voices within the Horde.
  • Thrall: But eventually, a new voice called to me. The cries of the elements drew me from my position as warchief…
  • Thrall: I passed the mantle of leadership to Grommash's son, Garrosh Hellscream. And I left to discover what had caused the elements' suffering.
  • Thrall: It was Deathwing. Years after his defeat, the great corrupted Aspect made his return.

Intro

  • Thrall: Your madness must come to an end, Earth-Warder!
  • Deathwing: I will tear your world apart…

Exchange

  • Thrall: Aspects, I call upon your aid!
  • Deathwing: You shall burn as Azeroth itself does…
  • Deathwing: I am inevitable… indomitable!
  • Deathwing: Your armor means nothing, your faith even less!
  • Ysera: Alas, to see a fellow Dragon Aspect fall to such corruption…
  • Ysera: The rest of us shall support you as we can.
  • Ysera: We shall channel our power into the Dragon Soul!
  • Alexstrasza: I will cleanse whatever corruption I can.
  • Alexstrasza: Deathwing's summoning of the final Cataclysm will destroy all life on Azeroth. Quickly, we must interrupt him.
  • Alexstrasza: He is completely mad.

Victory

  • Thrall: BEGONE!
  • Ysera: Strike true, Thrall! This moment can never be undone!
  • Alexstrasza: We dragon aspects have fulfilled our great purpose.
  • Alexstrasza: You are Azeroth's true guardians and the future of this world is in your hands.

Loss

  • Deathwing: I will destroy all other creatures who yet draw breath…

Idle

  • Deathwing: Your kingdoms crumble beneath my rage!
  • Deathwing: Pain… agony… you do not know them as I do!
  • Deathwing: Surrender all hope, and tremble before your fate!

HeroPower

  • Deathwing: There is no shelter from my fury!
  • Deathwing: I am the DESTROYER!
  • Deathwing: Shatter to pieces!

EmoteResponse

  • Deathwing: Insignificant!

Quote From Out of Cards

PreMission

  • Thrall: After Deathwing's defeat, I continued my work as a shaman alongside the members of the Earthen Ring. With my beloved Aggra by my side, the days went quickly.
  • Thrall: I did not see the storm brewing back on Kalimdor, where Garrosh unleashed his cruelty and might upon Theramore.
  • Thrall: As horrible as he had been, Jaina's desire for vengeance disturbed me even more…

Victory

  • Thrall: I pray you will recover from this one day, Jaina…

Loss

  • Jaina: We could have had peace, Thrall. But you threw it all away.

Idle

  • Jaina: I never should have trusted you. How could I have been so naïve?
  • Jaina: You knew Garrosh was dangerous. His father could not control his rage either!
  • Jaina: We both came to this land to start over. Now your people thrive, and mine mourn their dead.

HeroPower

  • Jaina: Suffer as Theramore did!
  • Jaina: Take responsibility!
  • Jaina: Everything is gone. Everything!

EmoteResponse

  • Jaina: I won't hear this!

Quote From Out of Cards

PreMission

  • Thrall: Though overwhelmed by anger, Jaina had cut to the heart of the matter. Garrosh had gone down a dark path.
  • Thrall: I next heard of his trespasses from my own former counselor, Vol'jin. I went to him. I saw Garrosh's malice with my own eyes.
  • Thrall: And though I resisted it with every part of my being, I knew I had to face him.

Victory

  • Thrall: You disappoint me, Garrosh. You are not worthy of your father's legacy.
  • Thrall: Leadership is a heavy burden—too heavy for some to bear. I had no desire to take it up again. I needed something more…
  • Thrall: When I was young, I believed I had no family, and when I learned who they were, they had already passed.
  • Thrall: But, even if your family is gone, it is never too late to make your own.

Loss

  • Garrosh: Under my leadership, the Horde will conquer all…

Idle

  • Garrosh: You once promised me a great destiny because of my father… Now you betray me.
  • Garrosh: I will never be the leader you were. I will be more!
  • Garrosh: You admired my father for the same reasons you reprimand me—our rage, our strength!

HeroPower

  • Garrosh: You are no more than a traitor now!
  • Garrosh: I answer to NO ONE!
  • Garrosh: Behold my strength!

EmoteResponse

  • Garrosh: You have much to learn…
