"Fanatic (Protection) (LVL 1)
Target a member of the Shadows at night.
You will give them a protection that will only last for this night.
You can target yourself.
Upon preventing a Shadow from dying, you then become a Terrible Prophet."

This was Yuesford's role before they lvled up.
Which means we know that by Frinckle's logs that Blink was also a shadow.
