Guild Wars 2 – Fight the Ice Dragon's Corruption

“Destroy any signs of the dragon's corruption, including his worshippers.”

Head over to Krennak's Homestead Waypoint. Just a little to the North of that you will find Tor the Tall. Talk with him to learn more about what is going on in the surrounding area.

Tor the Tall: “Hello there. How can I help you?”
Hero: “I hear you have grawl trouble.”
Tor: “We sure do. Those dragon worshippers across the lake are making the grawl crazier than usual. Head east across the lake you'll find the Sons preaching to the grawl.”

Just as Tor says, head to the East and you will start finding the signs of the dragon's corruption. This takes numerous forms so there is a small variety of things to kill or destroy. Look around for Corrupted Ice first. It rarely draws any addition aggro, respawns at a fair pace too.

The next few things are simple enemies: any Sons of Svanir. There are a good variety within that catagoery so they can either be easy or hard to take down. Just keep from being overwhelmed and handle as is appropriate for your class.

Finally, head all the way to the East into the opening along the eastern side of the lake. There you will find Ice Elementals and Icebrood Elementals. These also represent the corruption of the Dragon. Kill them all.

It is nothing too big to complete this quest in the end. Just search around the eastern side of the lake and kill anything that is corrutped, an Elemental or a Son of Svanir. When the quest is done you will receive the letter, “Great Job” with 75 copper:

“Hero's name, what a pleasure to have worked with you. Although Dragon's influence continues to spread, with your help we've slowed the spread of his corruption. Thank you! - Tor the Tall”
