If you have not completed the Wrathgate quest chain, there are major spoilers in here. I tried to make it as vague as possible, but they're still there. If you want to do the questline without knowing what all happens, I'd say go do it, then come back and read this.
Don't say I didn't warn ya.
The inn at Valiance Keep was doing a steady business, but no one paid much attention to the lone night elf sitting by himself in a corner. Alanon’s thoughts were in turmoil. It had been some weeks since his return to Northrend and the battle against Arthas, but the events of the past several days were enough to make him wish he had not come back.
He had gone straight to the Dragonblight, to Winterguard Keep, to give aid where he could. The members of the 7th Legion posted there had actually needed his help badly and he was kept busy. When he was no longer needed, they sent him on to Fordragon Hold to speak with Highlord Bolvar, who had sent him on to Wyrmrest Temple, to speak with Alexstrasza the Life-Binder herself. As a healer who revered life in all its forms, Alanon was so awestruck by the Dragon Queen that it was all he could do to speak.
But the news she gave him had been unsettling. The Scourge were trying to dig up an immense dragon skeleton nearby. If they succeeded, and Arthas raised him, the resulting frostwyrm would be unstoppable. Alexstrasza sent him with one of her red dragons to stop the Scourge, and they were victorious. That was the last thing to go right for a long time, it seemed.
Alanon picked up his mug and stared inside it without drinking. Whatever answers he sought, however, weren’t there, and he placed it back on the table. He sighed heavily. After a minute, he got up and went to the barkeeper for some writing materials.
He sat back down and began writing a letter.
"You may or may not have heard of what has happened here in Northrend. Highlord Bolvar Fordragon has been killed by treachery. Our Alliance stands at the brink of war with the Horde once again. This could not have happened at a worse time. I fear that I must agree with some of the others here: if we go to war against the Horde, Arthas will simply destroy us all. King Varian Wrynn does not see it this way, however, and pushes for the extinction of the only possible allies we have against Arthas. I fear it is only a matter of time. Be careful, all of you. There's no telling what might happen next.
He sat back and re-read it, then wrote out several copies and addressed them all. After a moment he pulled one out, and added a few lines.
Barraccus, watch your back at all times. There may be some willing to take revenge on any undead they come across, whether they are Forsaken or not.
He stepped outside and dropped the letters into the mailbox, wishing that his problems could be disposed of so easily. A freezing wind swept down the street, and Alanon had the disconcerting notion that it was the beginning of the winds of war.
