Hold a Crystal - Ch 2, Labyrinth FF

From that point, Sarah became gradually less surprised to have new crystals appear in her life.

At first, they came every two or three months. Then every 6 to 8 weeks. By the time she had many of them, she had gotten used to incorporating them in her Christmas decorations, and started wondering whether or not they'd do for around-the-year décor.

She never broke, sold, tossed out, or gave any away. Once or twice, Toby might have gotten his hands on one. Strangely, though, none were ever missing, and sometimes Toby ended up with a new rubber (or plastic) toy ball.  Sarah learned to smile and divert the subject whenever Dad or Karen wondered about it.

By the time Sarah was nearly done with her degree, commuting to the local branch of the big name public university, she had become so accustomed to handling them that she never thought about them anymore, and the memory that they used to trip over no longer jangled in recognition.

Or so her friends wondered.

More than once, Hoggle offered (and also tried to do without Sarah's notice) to remove them from Sarah's room and get rid of them. But the crystals never let him touch them.

Sir Didymus was relieved when Sarah stopped worrying over them, but worried when they ceased to seem special to her.

Ludo, as serene as ever as long as Sarah was safe, and he was out of the smell range of the Bog, probably had the closest sense of how Sarah was handling it: acceptance that something had yet to occur.

What the owl saw and knew from a treetop vantage point was that every few days, Sarah would retrieve a crystal. Not just any crystal, but a specific one. Somehow, she knew which one arrived when in her life. Generally, she would hold the very first one, with one or two others from various days, curl up on her bed, or the window seat, or lean against something, and gaze through those erstwhile wishes.

The sighs that never quite escaped her still reached her observer, and he continued to mark time.
