Valley of Echoes
The Valley of Echoes[85, 74] is usually the first area adventurers will visit in their journey into Icecrown. Located in the southeasternmost area, it can be entered through a naturally forming ramp from Crystalsong Forest or through flight.
During the war against the Lich King, the Argent Vanguard was the first forward base established by the Argent Crusade when they breached Icecrown under the command of Highlord Tirion Fordring. Located in the Valley of Echoes, it gave them a path into Scourgeholme, which the highlord hoped to conquer and remake into an Argent Crusade fortress.[1]
Phasing
First encountered
Before having completed quests in the area, Argent Crusaders are roaming the Valley of Echoes, fighting with Forgotten Depths Slayers. Some crusaders are bound in webs. Forgotten Depths Ambushers will occasionally pop out of a webbing and attack.
Scourge attack
After completing 
[25-30] A Cold Front Approaches, the Scourge will start attacking on the Argent Vanguard.
Cannons appear on top of the Argent Vanguard Towers. The Valley is filled with scourge of various sorts, and an occasional Frostbrood Destroyer joins the fight.
Aftermath
When [25-30] The Last Line Of Defense is completed the Argent Crusaders once again wander the Valley of Echoes cheering loudly near the dead bodies of the slain Frostbrood Destroyers and various dead Nerubians.
Various NPCs appear at (or move from the Argent Vanguard) a camp at the north end of the Valley of Echoes, just shy of The Breach. While a small group of crusaders guard the Breach from further Scourge invasions.
