Containment

A field guide to what lives in an estate.

Every one of these was met in a live tenant. Each record says what it does, how it got in, and how to go looking for it.

Specimens are composites. The creatures are real.

Classification

Dormant
Does nothing at all, and is armed the entire time.
Endemic
Found in most estates where somebody goes looking.
Active
Feeds continuously, and produces no operational symptom while it does.
Breach
Something has already come through. No longer a finding.
Greenfield event
Rebuilding the estate has become cheaper than correcting it.
