The Halloween Masque was a party hosted by David Xanatos and his family in 1996.
In a three-part plan to garner acceptance for the Manhattan Clan, Xanatos decided to host the party, where all of Manhattan's social elite would attend, and befriend the gargoyles there. After that point, only hypocrites would be able to discriminate against the clan. Xanatos, however, was unable to attend his own party, because the Illuminati sent him to the White House, where he was given his first true task by the secret society.
At the party, Brooklyn was depressed about Angela having chosen Broadway for her mate over him. Elisa, fraught over seeing Goliath with Delilah, went to the courtyard, where Goliath came to comfort her. Thailog appeared to reclaim Delilah, and stabbed Goliath in the stomach, nearly killing him. During the ensuing battle between the Manhattan clan and the Clones, Thailog collected blood samples from every member of the clan, including Elisa, Angela, and Bronx.
Owen Burnett brought Delilah to the courtyard, where she promptly ended the battle. Delilah chose to remain in the Labyrinth, the only place she felt truly free. Burbank, Hollywood, and Malibu elected to stay in the Labyrinth as well, but Brentwood defected to Thailog's favor.
Brendan Quarters, fuming that Margot had insulted his choice in costume, witnessed the battle between the clones and the Manhattan clan, and saw that Goliath was injured. He ran to Dr. Sato, and told him that someone needed medical attention. Dr. Sato, sans Brendan, appeared and was shocked to discover that Goliath was truly a gargoyle. Dr. Sato treated him, initially in the courtyard, and presumably moved him to the infirmary and continued treating him there. Goliath, fortunately, survived.
