The objective of Operation Flycatcher was to collect samples of aphasic lifeforms for study in a lab. The project was black listed as a failure, with a high rate of personnel loss, and cost overruns.
This was not the truth.
Also known as the Circle of Soul Stealing, a devious and powerful trap
"John. This is your final power. Precognition. Don't you see? The ability to know what is going to happen. And, if you know what is going to happen, then you can stop it."
Often considered only a vicious trap that preys on the fears of its victims, the Vattic Trap harbors an important secret.
A casual remark by one of the party about something met on a previous adventure leads to a summons to and grilling by the Mages' Guild (or equivalent), probably resulting in an expedition back to that area to recover the things for 'study' by the Guild. The party's presence will be 'requested' for this expedition.
