these later days of future lure

I've been called the phantom of the office. I've been called this because I often will show up when nobody is around, do what needs to be done and then disappear into the wee hours of the morning. Not too unlike those magic cobbler elves that would help out that kind old cobbler during the night. Only I've got no magic and at times, I'm probably a little more gruff than those elves. I'm more like a cranky gnome than I am a magic elf.
