Yesterday, Community Manager Sapience announced on the LOTRO forums an upcoming in-game event where each server will be challenged with helping his low-level hobbits make it to Isengard without being defeated. Players are encouraged to roll some hobbits of their own (up to level 10) to make the challenge more interesting.
The events will be streamed live at http://www.twitch.tv/turbine_sapience.
For more details on the event, be sure to check out the original post on the LOTRO forums!
