Brown mold is found in damp, subterranean areas such as caverns and caves. It is light to golden brown in colour. Brown mold feeds by absorbing heat, even body heat. Where brown mold grows, the temperature is below average. Direct sunlight or UV light kills it. Brown mold grows instantly from heat. If a torch is used in its vicinity it doubles in size. Extreme cold kills it. Instinct: Drains heat from nearby living things

• Dwells in caves
• Vulnerable to cold

They live in your skin. Or your organ meat. Or your eyeballs. They grow there and then, in a bloody and horrific display, burrow their way out. Disgusting. Instinct: To infect

• Burrow under flesh
• Lay eggs
• Burst forth from an infected creature
