mr1234, I need the chart to include the Part of Fortune to be able to fine tune the reading.
No one took it, you still have it somewhere and you are very likely to find it, although in relative terms, not very quickly.
The land upon which it rests is near water and a source of heat, possibly made of wood. Different directions are indicated, but North/East is predominant. It's very likely that it's around where you spend most of your time, but hidden near a "boundary" of some sort. Look where you study. Is there a spot near where you study that can be linked to both heat and water? Look there between things. Look near the ground level. It's likely that you dropped it or misplaced it as you were focusing your attention on something or someone important, and it distracted you from paying attention to it.
I still need a chart with point of fortune for better judgement. I hope you find it.
