Hi! It’s Angel Leigh McCoy, wordsmith on the Guild Wars 2 design team, and I get to tell you about the work we’re doing with the asura. The races of Tyria are each unique, in their own special-snowflake way, and the asura are the flakiest of all—which is why we love them so much!
Asura are diminutive, vibrant geniuses with chips on their shoulders. We first met them in Guild Wars: Eye of the North, but their history might surprise some people. Before 1078 AE (~250 years before GW2 present day), the asura lived underground, building their civilization in dark caverns. They rarely came out, and few other races encountered them.
