The Great Disaster
The worst terrorist attacks in history which resulted in all of the at time heads of each family dying and the resulting determent to the Parrish family
Terrorist Attack
On the 10th day of January of the day Monday, was the day of the bi-yearly meeting where the families all gather together to discuss current affairs, family business that's willing to go public, etc.
Little did the family know, within mere seconds, there was an explosion so great, it took out one-third of the castle and caused a wave of force to spread at least a 1 mile radius, causing people who are closer to either fall off their feat or at least fall to their knees.
This disaster brought upon the purge of the Parrish family and the country of Zion was to be annexed. While nobody resides in Zion anymore, the land has been claimed by each family and anyone who comes walking in is immediately apprehended and either jailed or released depending on certain circumstances.
The disaster has brought upon great anxiety in the world that has caused the families to not trust each other (to put it extremely lightly). What this'll branch out to has yet to be seen.
