When “Shadow in the Ice” was first pitched, many aspects of the episode were still left to be discovered. One thing, however, was certain: We were going to have an encounter with a deadly foe from Tyria’s past. Something sinister, spoken of only in whispers. A monster that players themselves had once caught a glimpse of more than a decade ago in Guild Wars: Eye of the North®. The creature whose dark influences created the first corrupted Nornbear and started a series of events that led to the very creation of the Sons of Svanir. We were finally coming face-to-face with Drakkar.
