To find the missing Justice League, Klaus, Zatanna, and Robin will brave the greatest terror of the holidays...a Christmas party. You are cordially invited to a winter solstice gathering of the strange and oft-deadly magical community at the Georgetown mansion of Baron Winters, one guest limit. After a performance by sirens and banshees, we will gather in the Baron's study, where noted demonologist Jason Blood will be giving a reading on the origins of the being called the Silent Knight!
