Resonance Residue
Resonance Residue is a rare electromagnetic phenomenon first documented by Professor Benjamin Holbrook during the Midnight Telegraph incidents of 1873. It manifests as a persistent energetic imprint left on conductive materials following exposure to intense temporal or paranormal activity.

Properties
Resonance Residue exhibits several unique characteristics that distinguish it from conventional electromagnetic fields:
- Maintains a stable signature for extended periods
- Resists normal electromagnetic interference
- Produces measurable effects on Sympathetic Materials
- Can be transferred between compatible conductors
Detection Methods
The primary tool for detecting Resonance Residue is the Holbrook Oscillator, which measures subtle variations in electromagnetic fields. Other detection methods include:
- Chromatic Analysis using specialized photographic plates
- Harmonic Resonance Testing with tuned crystal arrays
- Direct measurement using Sympathetic Conductors

Applications
Resonance Residue has found several practical applications in paranormal investigation and communication:
- Tracing historical paranormal events
- Enhancing Telegraph Enhancement Systems
- Calibrating Temporal Detection Equipment
- Identifying locations of significant supernatural activity
Notable Incidents
Several major historical events involved significant Resonance Residue measurements:
- The Midnight Telegraph incidents of 1873
- The Silent Bell phenomenon of 1868
- The Great Resonance of 1885
Scientific Understanding
Current theories suggest that Resonance Residue represents a previously unknown form of energy storage within conductive materials. The Holbrook-Wei Theory proposes that this residue forms when normal electromagnetic fields interact with temporal anomalies or paranormal phenomena.
