You may have heard a bit about TERA transforming into TERA: Rising and going free-to-play on February 5th (or, as we like to call it, tomorrow). That's still happening: You'll get to log in for free and play for free and do things for free and it'll be just wonderful. However, if you were hoping to drop some dough to pick up things like a mount, costumes, or elite status, you'll be out of luck for a few days.
Valkyon Outfitters, the place where meatspace money turns into cyberspace loot and 1337ness, will take a few extra days to be ready for business. You'll have to make do with checking out all the awesome new content without the benefit of a brand-new costume until the shop is ready to open its doors.
We know it'll be tough, but you can do this. Just wait a few more days to start flinging your money at the game.
