Ambassador Amnerys posteth:

We will bring the Free Realms servers offline on Thursday, February 14, 2013 at 8:00 a.m. PST (San Diego Time) for a Game Update. Anticipated downtime is around 1 hour.

This update will introduce the Achievement system, a couple of UI changes, and an update that will allow TCG players to start the Set 2 quests after completing Set 1.

While you're waiting, check out the letter from Free Realms Producer, c0braje7!
