That looks interesting, I make a search check for loot.
Wait... what comes at me?
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.
The PCs are exploring the catacombs beneath a Colosseum-in-Rome type of structure, when they come across a foul-smelling, stagnant, ankle-deep with algae, public mass latrine. Countless urinals of marble, line this rather large chamber equally crafted of marble. Whatever system of plumbing once worked here, has not in many years. Old graffiti lines the stained,dirty walls, prominently bolded are such intellectual poetic musings as, "Urine For It Now", "I Pee Therefore It Comes" and "Now Urine Trouble".
A few moments after the PCs get to take in this unpleasant location, they hear the low rumbling of ancient plumbing and rather large Urine Elemental rises like a great, wet, wave of filth to attack them. The creature reeks and exudes noxious debilitating fumes, while its liquid strikes burn flesh like acid.
