Magical Contamination Control in Faerûn: Protocols for Arcane Incident Response
From the ember-lit forges of Neverwinter to the mist-cloaked alchemy halls of Thay, the production facilities of Faerûn hum with magical activity. But when spells misfire, potions backfire, or extraplanar residue leaks into the material plane, the consequences can be dire. For the Waterdeep Trading Company and other guild-operated workshops, such events demand swift, structured action, lest a single miscast alter a year’s worth of inventory or spawn something best left undescribed.
This article outlines the key protocols used by responsible enterprises to isolate production lines following arcane incidents. Whether managing potion bottling lines or enchanted fabric looms, understanding and deploying magical contamination control procedures is essential to safeguarding workers, goods, and realms.
What It Is
Magical contamination control refers to the standardized set of responses enacted when production environments are compromised due to:
- Alchemical Failures: Unstable mixtures or expired ingredients causing explosive or mutagenic reactions.
- Arcane Feedback: Resonant energy loops from misaligned enchantment channels.
- Planar Anomalies: Unexpected breaches to or influences from elemental, fey, or infernal planes.
Why It Matters
Unchecked contamination does more than damage product. It risks:
- Cross-contamination of inventory
- Arcane drift corrupting enchantment runes
- Worker injury or polymorphic exposure
- Violations of guild regulatory standards
- Reputation loss due to cursed or unstable shipments
For guilds operating under the Arcane Artificers & Alchemists Union or exporting under planar trade compacts, containment compliance is legally and ethically mandated.
Components of a Magical Contamination Protocol
The Waterdeep Trading Company employs a tiered response system known as the Aetherlock Sequence. This model scales with severity and includes personnel, magical wards, and procedural safeguards.

Isolation and Neutralization Techniques
When contamination occurs, the first principle is always containment before cure. Methods vary by trade but commonly include:
- Arcane Lock and Ward Circles: Prevent spread of animated objects or malicious enchantments
- Material Sequestration Fields: Isolate ingredients or products suspected of instability
- Spellflame Purge: A controlled cleansing fire that neutralizes enchantments (used only in Tier III or IV events)
- Planar Anchors: Restore equilibrium when foreign energy leaks are detected
Worked Example: Fabric Infusion Collapse
At Lara’s Fine Fabrics and More, a batch of invisibility-thread cloaks became unstable after a moonstone filament from the Feywild proved incompatible with standard weave matrices. Within moments, the visibility of workers and materials began fluctuating wildly.
Response Summary:
- Tier II initiated
- Loom Room sealed with a triple-layer ward
- Cloaks marked with non-visual sigils and relocated
- All affected workers underwent charm reversal and planar detox
Total downtime: 6 hours. Inventory loss: 4 cloaks. Lives lost: 0. Reputation: Preserved.
Realms-Aware Considerations
Contamination protocols differ by location and infrastructure:

Final Thoughts
Magical contamination is not a matter of “if” but “when” for any serious producer in Faerûn. By embedding strong protocols, both mundane and magical, into daily operations, guilds like the Waterdeep Trading Company not only protect their profit but honor their oath to the safety of the Realms.
The arcane may be volatile, but through discipline and ritual, even the most unstable magic can be managed.
