Hourglass. It counters all the motions of the universe and maintains you in exactly the same location
with respect to Earth's surface, regardless of how you use it. Without that protection, it is true, you
would perish the instant you traveled in time, for you would in effect be flung deep into the core of the
planet or out into the vacuum of space. That Hourglass remains with you and protects you from all
mischief, its ambience forming your cloak." He smiled engagingly. "It even protects you from My
mischief."
