Once you are ready to go, Algorthas moves out from behind his desk and addresses you briefly, "Well, good luck, lords and ladies, and may the gods watch over you. You are undertaking quite a task and without you I'm sure Istivin would soon be in very dire straits indeed. Don't underestimate the power of what you are investigating. It has been able to subvert the mightiest wizards and soldiers that Sterich has to offer, and twist their minds and hearts to mistrust and hatred." With that we waves goodbye and returns to his chair, looking more like a frail, old man than ever before.
As you emerge from the strange basement room, Anastasia turns to all of you, a stern look of concern on her otherwise fair face. "This is quite serious. My sisters and brothers in service to Mayaheine should be made aware of what is happening. I will go to them and warn them of what the seer has told us. I will join you as soon as I can. Good luck my friends." With this she smiles warmly and heads off south toward her goddess' temple.
You quickly make your way out of the old temple back out into the odorous streets of the Abandoned Quarter. From time to time as you walk towards the Keep you can see strange, mismatched eyes peering out from behind walls or through broken windows, watching, observing. If approached or spoken to they quickly disappear from sight and do not reappear again.
After a short work you leave the buildings behind, and head out over the grassy fields which surround the Promontory. The walls and outer towers of Krelont Keep look down on you with stern and cold majesty, unaware of what is happening around them.
You can smell the Effluvium long before it comes into sight around a corner of the Promontory. It is a small lake into which countless sewer pipes, large and small, empty into. The foul-smelling, murky brown water ripples lightly in the cold morning wind, but nothing seems to live in this fetid soup. Most of the drains which empty into it are only a few inches in diameter, but some are as large as four feet across.
After only ten minutes of searching you come across the sewer entrance marked with the builder's sigil which Algorthas had drawn for you. It is out of sight of the keep's watch towers and no homes are built nearby, so anything you do in this region should go unnoticed. The tunnel itself looks hardly inviting; merely four feet in diameter, the thick, nasty off-flow that sluices into the Effluvium pool is an affront to both eye and nose. Looking inside, the niter-encrusted walls slither with things better left in the dark. The tunnel's incline is slight, but it looks as if the slick surfaces will make clambering up it a distinctly unpleasant experience. No grate or gate can be seen in the tunnel, although you did not see any in any of the larger openings either.
