Demona and the Captain of the Guard were angered by the disdain with which Princess Katharine and her people treated the gargoyles who defended them nightly. They plotted to lure Goliath and the rest of the gargoyles away from Castle Wyvern at night, making sure they could not return to the castle before sunrise. The Captain would sabotage the humans' defenses, allowing the Vikings to easily take the castle that night. The people of Wyvern would be taken captive and the gargoyles would be free to resume life as they had known it before their alliance with humans. The plan went awry almost from the start. Goliath did not wish to leave the castle unprotected and although both Demona and Othello offered to accompany him, he pursued the Vikings (actually only a few soldiers leading horses as a decoy) with only Hudson. Since nearly the entire clan would still be present at Wyvern Hill that night, Demona reluctantly agreed with the Captain to modify the plan. The Captain signalled Hakon, the Viking leader, to attack the following day while the gargoyles slept and he vowed to Demona that he would guarantee the gargoyles' safety. Fearing what the other gargoyles would think if they knew of her treachery, Demona did not warn any of her clan of the coming attack, instead leaving the job of protecting them to the Captain. She did, however, flee the castle shortly before dawn, abandoning her clan to their fate. The Captain tried to defend the sleeping gargoyles that day, but Hakon did not trust his claims that the clan would not pursue his troops once the humans were gone. Hakon and his men shattered the gargoyles in their stone sleep, all but destroying the entire clan.
