Dialogue
 * "The Priests of Balthazar are quite upset, it seems. They sense grave danger on the horizon, and while we have sensed this as well, we do not feel that crushing the spirit of the local population is the best way to prepare. Of course, the Priests of Balthazar have been less than receptive of our alternate solutions.
 * "Against our better judgment, we have agreed to meet them in battle with all the forces we can muster, so we can show the residents of Tyria once and for all that, with hope and camaraderie, we can survive anything. If you wish to serve Dwayna and Melandru, speak with Melandru's Watcher. Should you wish to join forces with Grenth and Balthazar, you should speak with the Champion of Balthazar. Both can be found in either the Temple of the Ages or the Chantry of Secrets."

Walkthrough
While in this quest, your skill bar is replaced with Snow fighting skills.

Enemies keep spawning until the Beacon they spawn from is destroyed. There are two beacons to destroy.

Some general tips:
 * Ice Fort is an enchantment, so bringing a +20% enchantment mod can help.
 * The generals, champions, and beacons all count as spirits, as such cannot be hexed and are immune to the available conditions.
 * Avoiding groups and aiming for the beacons is a way to complete this quest quickly. A team doing this may complete in under 7 minutes.
 * Once one beacon is defeated, it is usually becomes easy to defeat the second beacon, as your reinforcements outnumber the opposing forces 2 to 1.
 * The defeat of a Champion or General gives a morale boost and recharges skills. This can be of use as these foes can use blizzard on you, giving you a free recharge of a prot skill that you may need to survive the duration effects of blizzard.
