"Which one? Oh, him. He be Pancratius. Yeah, he's a bit moody, but he's all right when you get to know him. Ya see, back in the day, and by that I mean his day, before you an' I were born, he was a big shot. The gods loved him, and one day, he asked for a gift that turned out to be a curse. Once he figured out the horrible side o' his gift, he sought out an oracle, to figure out how to get rid of it. Ol' Pancratius ne'er did tell me what the oracle said. The gift? Didn't I tell ye? No? It be immortality."

Brief bio of a space intel officer
The BRS Gwynith is an air ship of the Byrlothian Resistance. She is sentient, needing no crew to fly or man her, though she generally has a crew aboard for doing repairs and to go where she cannot.
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.
