It's a Brave New [Sixth] World
The 2016 Drake Hotel Incident
On May 16th, 2016, a terrorist struck the Drake Hotel in Chicago. Medical experts indicated that the nerve agent, HCN7, was untreatable by modern technology. Those afflicted were declared victims of the attack and pronounced dead, though many were subsumed into cryo storage by Trellix Medical Holdings Corporation for the possibility of resuscitation later. At some point in the following 60 years, a cure or treatment was discovered, enabling the restoration of the victims to health.
