From the EQ2 Forums:

We are inviting the most fearful, dreadful and simply awful creatures to the frighteningly decorated Community Lounge to celebrate the Nights of the Dead holiday with us. Show off with your costume creations, partake in a variety of unique drinks, and meet new players!

The community team will be hosting a Nights of the Dead Masquerade Ball on the Test Copy server.  Go to the docks in Sinking Sands at the proper time and date and take the portal to the community lounge.  Find out when, after the break.
