For the Ninth Fleet Imperial Ball aboard the <Imperial Accord> flagship Resurgence, the ship will be publicly listed.
There is also a custom channel for the event. In SWTOR, type /cjoin Accord_Ball to hear announcements and such. The channel will be IC but can ask questions in (( )).
The main event is on the Bridge Deck in the last room before the Officer Deck; however, all spaces are open with critical systems powered down and secured. A heavy marine presence, as well as the Ninth's Shadowguard, are meta'd throughout the ship to ensure safety. The event is Imperially sanctioned, meaning that no one should expect to cause trouble without heavy Imperial backlash. Enjoy!
