In either True Lineages, the Core book, or some other book... There is a mention of something to the effect of "the Quaesitors were given new investigative powers they previously did not have in order to avoid another schism war."
Exactly what might these "new" and now standard investigative powers be?
It counts, because I'm running a game in 801, and while I think I figured this out before (likely decided something myself and never wrote it down), I can't for the life of me find it. Any suggestions would be great.
