Turbine has announced that the content update Prince of Rohan will be coming to Lord of the Rings Online on Monday, December 12. This update continues the Epic story in-game and adds 5 new Isengard instances.

This is the first patch update with content additions to the game since the release of Rise of Isengard in September. At the release of that major content update, Turbine promised more content, much of it focused on Rohan and the Isengard Foundry.
And so LOTRO continues its inexorable march towards Mordor.
