What began today as a rumor, has now been officially confirmed: Sean "AshenTemper" Dahlberg has departed Bioware.

Sean served as Community Manager for the Star Wars: The Old Republic community, and this story originally began as a simple rumor posted to the official SW:TOR forums this morning. The rumor asserted that, according to "various sources" Sean had left the company. The post's author, "Lauren", pointed to Mr. Dahlberg's Twitter account, which no longer reflected his position at Bioware, to reinforce their claim.
Earlier tonight, Bioware's Senior Community Coordinator Joanne Laroche confirmed the report, explaining that Sean had indeed left the company:
Hi Everyone –
Sean Dahlberg has recently left BioWare. We would like to thank Sean for doing a great job building the TOR Community and we wish him well in his future endeavors!
Best,
The Star Wars: The Old Republic Team
We wish Sean all the best wherever his future takes him!
