The Federal Campaign
Secret InvasionThis flow tracks the transformation of scattered emergency calls into a national operation designed to find nests, kill adults, and prevent biological contamination.

A Scientist Alerts Officials
Laboratory evidence
Leslie Bickers identifies the newly hatched animals as sliggers and contacts her superiors. The living specimens make the threat undeniable rather than anecdotal.
Federal attention
Gina Taylor recruits Ron Tully and Andy Carlyle to examine the animals. The response begins as scientific consultation, but reports of attacks quickly turn the assignment into emergency work.
A Public Warning

A Public Warning
Connecting accounts
Mason alerts officials in other states, while researchers and law enforcement compare locations, witness descriptions, and physical evidence. Repeated attacks establish that multiple nests exist.
Preparedness over reassurance
Authorities warn coastal residents to stay away from water and avoid approaching suspected nests. The purpose is not to provoke panic but to reduce preventable encounters while a larger search is organized.
Military Forces Mobilize

Military Forces Mobilize
Reinforcements arrive
The National Guard and Army Reserve join local departments, while the president also directs the Coast Guard to assist. The response now has personnel capable of covering far more ground than scattered local patrols.
A national footprint
Separate units are assigned to coastal regions and river systems. The mobilization marks the recognition that this is not a conventional wildlife incident but a fast-growing threat to public safety and ecological stability.
A Coordinated Field Method

A Coordinated Field Method
Finding likely habitat
Teams focus on dark, wet places near water, including grass beds, culverts, sewers, and sheltered shoreline pockets. Local knowledge and scientific observations guide where to search.
Reducing missed nests
Mason advises a concentrated, section-by-section sweep rather than thinly scattering personnel. The method sacrifices some speed in exchange for a more complete clearance of each area before forces move onward.
The Crisis Is Declared Over

The Crisis Is Declared Over
A final accounting
After thousands of people search coastlines and waterways, authorities report that the infestation has been eliminated. Military forces return home, while local agencies continue checking areas for missed signs.
Relief with unanswered questions
The immediate threat recedes, but the origin of the creatures and the substance associated with the old submarine remain unresolved. The end of active operations is not the same as complete scientific understanding.
