A Natural Anomaly

Exploration Stage: House on the Hill
From: Martha
Description: You say the creature wanted to deprive the City of a colorful Halloween? There is another possibility. The Curse of Poisonous Crowns also corrodes colors and causes them to fade. Find my tree spray and we can test it out.
Completed: My enchanted tree spray didn’t restore the flowers’ hues. This curse might be rarer, and more dangerous, than I thought. We’ll need to deploy advanced measures.
