Backing up a moment, Our heroes convinced the Swamp Folk to assist them to get into the sewers inside the walls again. The Swamp Folk agreed to take them down into the restricted level of the Tsu'urum to lead them under the walls. They knew of an old Clan house there of the Great Stone Clan, which contained a labyrinth, which led, among other places, to a passage. The party would have to travel in darkness, so as not to attract what might reside in the labyrinth. But the Swamp folk, who are sensitive to “wrongness”, knew a way through the labyrinth, and would guide them.
So, hand in hand, they all made their way, quickly and silently as possible, through the maze, with their non human guides leading and taking the rear. Suni toyed with the idea of detecting foes, but, decided not to risk attracting attention with a spell, even a psychic one. The came out, and were given directions to a room that would lead back up into the sewer levels, and were left to their task. They were advised not to try to take this way back out.
Once back in the sewers, they moved downstream until they found a junction, just above the SW gates, leading to the river. They split into groups, to try to avoid looking conspicuous, but, somehow, they managed to attract the guards notice. Still, the guards let them pass without question – there was nothing technically illegal about being in the sewers, even if their arrival from that direction seemed odd. Technically, the guards were there to keep people out, not interfere with people who were already inside. So the party moved back upstream to the north, and eventually found the sewers that should put them below the Temple of Avánthe from the Red Hat Ditlána of the mid 1700s. And with much searching, they found the trigger to open a wall, and go in.
They found themselves in a supply room, off two converging halls, with the sound of chanting coming from each hallway. The halls were empty, and they knew it was getting on in the day. They assumed that rituals were in session and they decided to take advantage of this to look around. Down the right hallway they found three doors, two apparently private quarters, one a communal quarters, and a dead end, leading to UN-excavated space. Down the left they found Lavatories, and an office. Both directions seemed to flank the main ritual hall with doors that probably led inside.
Further left they found the smell of cooking, and, accidentally ran into slaves carrying Hot water to ritual baths, but the slaves were too busy to take notice of which priests were in the hall way. They found a side passage that led to administrative rooms and, in that section found the library. It took a little time to figure out the organization, but they did locate the book “A history of the flood of 643 and the appearance and disappearance of the Irriguous Dead”. They purloined it, and a few random others, and beat back to the storage room. Unfortunately, they still had not found the mechanism to open the door from the inside. And the ritual ended, so they hid back in the stair well. Slaves brought ritual paraphernalia into storage, and left and the halls outside became much more active. Another thorough search of the room, and still no mechanism. It was late, and eventually, the halls quieted down again. The midnight ritual to bring back the light began, with a skeleton crew of junior priests and priestesses, and the ranking members retired. A quick journey into the hallways found “Silence, I slumber”, Méshqu plaques on various doors. And time ran out for the session...
