The Committee on Diabolism is off to a good start, but the one thing it can't do - the one thing it is explicitly prevented from doing, by order of the archmage - is expel the diabolists it finds from the convention. That means that in addition to their plans to purge the nobility, they also need to work within the system to keep diabolism out of the constitution as much as possible, and not everyone is going to be as easy to identify as the Erecuran was. Ideally she wants someone on every committee, to oppose the ideas when they're raised and to warn the other members before a proposal comes to the floor, but for the moment she'll settle for the important ones like the rights and armed forces committees.
For the moment that takes the form of hanging around where convention goers frequent and sounding them out on the subject, though she really wishes right now that she was a proper cleric with detect evil.
