After the gargoyles were driven out of Castle Wyvern, Elisa brought them here, for them to use it as their home. They soon settled into the clock tower, and lived there happily until Robyn Canmore destroyed it. The clock tower is since being rebuilt, though in a slightly different style. Even after the clock tower’s destruction, its ruins were the site of Goliath and Elisa’s first battle with Castaway.
Real World Background
The clock tower is fictional, of course, but similar structures actually do exist in New York.
