Foresight

The Wizard's Glass is a round glass ball that glows pink and offers the onlooker a glimpse of things that other people are doing, most frequently in the present but sometimes also in the past or future. The ball is a dangerous, intoxicating thing, as Rhea of the Coos learns when she keeps it for the Big Coffin Hunters. Rhea takes pleasure is watching the evil things people do to each other and is so wrapped up in what she sees in the ball she neglects care for herself. When Roland Deschain kills her snake, Rhea only wraps it around her neck and lets it decompose there. When she eventually emerges from her home, others are shocked at her mangy and malnourished appearance. When others see the glass ball, it also compels them to want to hold and use it. Eldred Jonas in particular feels drawn to it...
