The end of an Era has come. Magic is broken. New Heroes are needed to face the challenges of the new Age!
Some tragic event several years ago has sent the Chronomancers into hiding.
"years ago" doesn't apply to Chronomancers...
In the endless moment of now in which the Chronomancers exist, and event is occurring that they have not figured out how to solve; which means that for the moment in which all others exists now, Chronomancers are hiding.
...but, when will then be now?
You advertisement does not go unnoticed...
I also report the crime to the constables, and offer to pay for a chronomancer to come investigate the scene to identify the perpetrator.
So you're saying they pay the bill I sent them? That worked better than I expected!
Are the results of divinations admissible evidence in criminal investigations?
Did the constable's investigation turn up anything useful?
