Guild Wars 1 players are familiar with the Jotun race, mostly as "the giant creatures that won't stop KDing me," but they're going to have a continuing and more involved presence in Guild Wars 2, according to the ArenaNet blog.
Ree Soesbee took a close look at this race in the newest ArenaNet blog post, "The Savage Pride of the Jotun." In the post, she explains how the Jotun have essentially devolved over the years thanks to infighting: "Over the centuries of their existence, the Jotun have fallen far from their state of grace, losing command of technology and magic they once utilized, and remembering their place as kings of the land only in legend and story."
The post delves more deeply into the past and present effects of this change, then switches gears for a behind-the-scenes look at the race's creation. The full post is a good read for anyone interested in the game from a lore or development perspective.
