Chronal Circle

You draw an arcane circle and fill it with iron dust to show a projection of an event that happened at any chosen time, as set by the caster. A soundless image manifested by chronal magic, created by the iron dust,  will appear and show what happened at the time for 5 minutes or until concentration is broken.

The image created cannot be interacted with or changed in any way. The amount of year in the past that the circle can go is based on levels put into the School of Chronurgy. At level 3 it is 100 years, at 5 levels is 200, at 8 is 400. The list goes on in an exponential growth pattern of every 3 levels the amount of years doubles.
