Lord of the Rings Online is offline as of now (6AM ET) for an update to the new Book 11, Defenders of Eriador. There are updates to Minstrels and Lore-masters, player housing, a Balrog and more in this new update.
All things being equal, LotRO is set to return around Noon ET. If you're looking for something to while away the hours, check out some of our other great content, read the patch notes and save yourself valuable time downloading the patch (900MB, so get in early)! The battle against the Witch King's minions returns at Noon!
