Heroes of the realm, hear me - the Horde calls upon you for swift action!
A call to arms has been issued for all able bodied individuals to take up arms against the Scourge! Rumors fly of new threats rising from the ruins of the Eastern Kingdoms. They loom to the east of the Undercity, in the northern reaches of the lands now known as the Plaguelands!
Heroes of the realm - seek out High Executor Derrington, who has set up his base camp at the Bulwark, east of Tirisfal Glade!
Welcome to the Plaguelands, hero. This is one of the most dangerous frontiers in Azeroth, with the looming threat of the Scourge to our east, and then even further still eastward from there. I am glad to hear that the call of duty and service to the Horde did not fall on deaf ears with you!
If you are ready to get your hands dirty, then there is plenty for willing and able heroes to do here on the edge of the Plaguelands.
