There are two stories to the Cursed Cup of Immortality, the one that was fabricated and sold to adventurers upon return, and the real story.
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.
Teenagers who run away from home to live in the wilderness may become feral. As they become more and more feral, they gain some supernatural powers (a la Peter Pan - ability to fly, things they imagine come true - possibly quite powerful), but at the expense of their humanity and ability to speak, comprehend complex subjects, etc. Maybe they have a leader: the most feral of them all.
A regression into a fantasy childlike state.
