Allergies are the body's overreaction to typically harmless substances such as pollen, dust, or animal dander. They may be seasonal, food related, or environmental.

Symptoms can include, but are not limited to:

• Coughing
• Hives
• Rashes
• Sneezing
• Trouble breathing
• Watery eyes

The Dwarvish merchant, Eregrun, is allergic to Blue Ichor, produced by the Insectoids. When exposed, violent sneezing is his typical reaction. Symptoms improve when the allergen is removed from his presence.
