Timely Gate Crashers

Did you see that giant mechanical monstrosity just walking around in the dunes outside? How about the icky shadowy Sha of Anger? Or that big frost giant in the north? Yeah, they aren't native to this area. They tell me the timeways are screwy around this time of year. They have asked me to organize a clean-up crew. Would you be up to the challenge? If you like this challenge, I have another for you as well.
