Seeing into the future?
Through out magick there are people who believe in future sight. Although some people over dramatize things by saying my predictions are 100% right. In fact if someone does tell you that don't go to them for predictions.
Future sight is just seeing what could happen in your future. Your future changes depending the choices you make. What happens in one future could be different from what actually happens.
Seeing into the future can be done in many ways, some people use tarots: Special cards filled with energy. Or they use divination; the ability to see into your future. Now the crystal ball may help but in most cases is a myth to legend.
