The Halloween demons are not happy. Not happy at all. They didn't get invited to the Monster Mash Bash last year. Although they have been invited this year, they think they are being mocked. Let's just say they are "steaming" mad. Will they attend? Maybe you can ask them, if you can handle the heat.
Cache is a red lock n lock container. It can hold small trade items. Please bring a pencial. Use stealth and hide cache the same or better than you found it. Happy Hunting!
