Ancient Illusion

To be used in conjunction with a Time Shifter. 
Place the components on the open pages of the book. Say ”Time Shift” and the spell will take effect. Any creature that touches the spell caster or the book will join in the illusion. The spell triggers an illusion in the mind of the creature it touches, enabling them to experience the Time Shift. The spell ends if the caster loses concentration or the Time Shift ends.
