Hearing this news, Patrick was absolutely delighted. He had been worrying about finding a good excuse to intervene in the affairs of the Eastern Plaguelands, and Taelan had brought it up himself. This was simply wonderful.
If the Blood Elves intervened in the Eastern Plaguelands on their own initiative, it would certainly put all the Undead there on high alert for developments near the Elfgate. Moreover, even if the early fighting went smoothly, Kel'Thuzad would later retaliate by sending the Undead to attack the Blood Elf forces on a massive scale. If the humans decided to avoid the brunt of the assault and fall back to Light's Hope Chapel, his people would certainly suffer heavy losses.
A place like the Eastern Plaguelands had already been thoroughly contaminated by the plague, and the dead buried there were beyond counting. No one could gain an advantage by fighting there. Moreover, anyone who lacked sufficient strength might even be encircled and wiped out by the Scourge.
Although the Kingdom of Lordaeron had already been destroyed by the Scourge, sovereignty over the Eastern Plaguelands remained an issue. At the very least, survivors of Lordaeron such as Tirion Fordring were unwilling to relinquish their identity as people of the Kingdom of Lordaeron. This also explained why, after splitting apart, both the Scarlet Crusade and the Argent Dawn accepted help only from Alliance and Horde adventurers while refusing intervention by official powers. This was precisely where the problem lay.

Although Lordaeron now existed in name only, quite a few of its people remained. At
