Grim’s Haunted Mansion: The Halloween Spooktacular

Ah, Halloween! If ever there were a busiest time of year for our dear overlord the Grim Reaper, this would be it. With that spookiest of holidays on the horizon, he’s soon to have his work cut out for him: looming, lurking, glowering, and quite possibly some swooping. Last year, he took a little vacation beforehand just to clear his head before diving into the fray, and this year, he’s had the courtesy to leave HQ a little note about his intention to do the same. We do hope Grim has fun.

But besides his message to HQ, Grim has also left us a special message for all of you, Eyewirers! The opportunity of a lifetime awaits.

October 20th is the day just after the new moon. From that date until the moon’s first quarter, Grim’s Haunted Mansion will manifest itself on Eyewire. Further details of your housesitting mission are below!
