Emissary

The emissaries are members of the Alliance that were sent in representation of a high rank commander or king. During the Third War, three of them appeared.

A Dark Covenant
After Kael'thas repaired three observatories, Lord Garithos took his forces to battle the Scourge and left Kael awaiting orders. The next day, an emissary arrived bringing news from Grand Marshal Garithos. The message said that the observatories Kael had repaired detected a large undead force lead by Dalvengyr and that he had to crush them before they could march on Dalaran. Kael was too confident that his forces would defeat Dalvengyr easily, unfortunately, Lord Garithos also ordered all foot soldiers, cavalry, and support teams to meet him in the front lines, leaving only the blood elves. Kael demanded the actions of Lord Garithos, but the emissary just replied that Garithos had great confidence in Kael's "abilities" (in a racist tone of voice) and wished him luck saying "Be creative".

To Tame a Land
During The Founding of Durotar, Thrall received a letter from the human leader to meet in Razor Hill. Rexxar was informed and suspected a trap, so he went in the place of Thrall, yet when he arrived he did not meet the human leader and instead found an emissary. The emissary was surprised to see a half-ogre instead of the orc Warchief. He revealed to Rexxar that he wanted to kill the warchief but would settle with killing Rexxar. As Rexxar suspected, it was an ambush from Kul Tiras, but he had brought with him Chen Stormstout, Rokhan, and Misha. They fought back and killed the humans. With his last strength, the emissary told Rexxar that it was only the beginning of a greater invasion, dying moments later.
