Predating the coming of the Rifts, Casa Loma survived the great cataclysm and was eventually taken over by Plato as both his home and where the Council of Lazlo meets to decide upon the major issues of the state.
Casa Loma (Spanish for "Hill House") was a Gothic Revival style mansion and garden in midtown Toronto, Ontario, Canada, that well predates the coming of the Rifts. It eventually became a historic house museum and landmark in the city later in the 20th century. It was constructed from 1911 to 1914 as a residence for financier Sir Henry Pellatt, a relatively famous person of the time. The architect was E. J. Lennox, who designed several other city landmarks throughout the first half of the 1900s. Casa Loma sat at an elevation of 140 metres (460 ft) above sea level but is a bit lower than that since cataclysm occurred (approximately 100 metres/320ft)
Due to its unique architectural character in Toronto, Casa Loma had been a popular filming location for movies and television. It was also a popular venue for wedding ceremonies, and Casa Loma could be rented in the evenings after the museum closed to the public for any variety of events.
This continued into and through the 21st century in this capacity having any number of visiting dignitaries being hosted for summits and photo ops, right up until the rifts arrived in 2098.
No one knows for sure why but Casa Loma survived the initial cataclysm relatively unscathed only suffering minor cosmetic issues to the structure itself even though much of the city around it had been torn asunder. Many have speculated that it may have had something to do with the materials used. Others think it is the specific style of construction. Others still think it is because of a minor Ley Line located under the facility.
After the Rifts hit, a number of people and beings tried to lay claim to the location as a base of operations. The area itself had a high turn over of "ownership" over the 200 year dark age before finally a group chased off a number of entities and being that had tried to enslave the locals. They too took Casa Loma as their "base" of operations as it were but this time things managed to stabilize. With the arrival of more and more benign and peaceful peoples and beings looking for a home to just live their lives, Lazlo grew from this place.
Today it serves as the "city hall" of the City-state with the various councils keeping offices and meeting here regularly to discuss any number of issues facing the city-state. It also serves as symbol to the rest of the city as reminder of the past and the ability to survive and endure.
