Valweni Moth

The deep wilds of Valdar are home to the valweni moth, a particularly large species that is capable of morphing the material realm around them. These moths are named directly after Valweni, the mysterious Goddess of Illusion, and possess large black-spotted wings, with a wingspan of 3 to 5 feet. Valweni caterpillars defend themselves with an illusory shroud that makes them difficult to detect. The adult moths are far more powerful in their abilities, with a natural camouflage and an aura that can make the landscape around them appear false to observers. If an attacker gets close enough, they can assault it with a barrage of illusions that can blind or stun.
When a large group of moths gather, known as a delirium, the effects on sentient creatures around them can be severe. Adventuring bands have reported hallucinations, nightmares, and fatal sleepwalking while in a delirium's sphere of influence. However, valweni wing dust is a highly sought-after ingredient in potions, alchemy, and other magical creations, so there are plenty willing to take the risk.
