The real question was where would they go first. They headed down the path and they were going to explore the various possible directions they could go, and there were many, although a few of them went into the same room. Most of the rooms ended in mud and they were still scared of the mud from the last time. The mud would have been a difficulty, the mud would have been difficult to traverse, but it was harmless otherwise. The big tight that it would have done is made the terrain difficult to cross; it would reduce their speed by half. Technically, the mud would have been more difficult for the Gnome as it was a foot or more deep. They chose to follow and explore the regions where the path was dry, well not outright mud. I did mention that they could see tracks heading one way, as one of the residents on the first level worked on the second level. They followed the tracks.
They explored one of the possible directions until they discovered water and then they retreated, which if they had continued they would have discovered the main treasury. Nothing big, just 300pp, 600gp, 1000sp, 1000gp in jewelry, and 500 go in gems. Which would have really had been the big haul. Oh well, they did not know that I had planned on a quick retreat as the cave complex collapsed.
The group continued up to a door where the tracks seemed to enter. The problem was that they were without a light source, all the characters could see in darkness but in black and white with grey scale, but that means that it is more difficult to discern what they see, they are at disadvantage in fact. They opened the door and they entered a large room with a zombie. One zombie would not last long, they unloaded on the the poor zombie and dropped it almost right away. The problem was, this was not a zombie, but a 1e Coffer Corpse and it was only harmed with magical weapons, which they had none and magic, which they did not try to use; I kept track of all damage that they 'did' and told them that the zombie took their damage and appeared not to slow down. Fire and other spells cause damage to it but nothing else. The zombie 'died' and then rose up as a special attack that caused fear, which a lot of the characters failed their saving throws for and ran in terror. They ended up causing over '100hp' of damage before it really died.
Next they happened upon the location of the prisoners and they freed them and rested for an hour before continuing on. They came on to a cleric and a Wight that were waiting for the characters, because the Cleric knew the Coffer Corpse was fought. I was toying with having two Wights but I decided only one. With two attacks every round, two mig have been too much, especially since the Wight is immune to normal weapons. The fight did not last as long as the last one. They fought with more magic and the ranger shot the Cleric with an arrow and then the Bard cast sleep on him; walked up to the sleeping Cleric and cut his throat. The wight died again a little later. They decided that they would destroy the alter and in the process they activated the secret door and they found a passage that ended at a wall. They broke the wall down since it was made of mud and discovered the rear entrance to the Naga chamber.
They had surprise.
They attacked.
The Druid became a spider and shot a web unto the Naga. The Bard inspired the main fighters to move to attack and they did so effectively. The Ranger peppered the Naga with arrows. The naga acted last in the fight order which meant a free fighting action for the group. They had nearly killed the Naga before it could act. It acted and it broke the webs and dimension doored to a different area of the combat. The beast was half in the water and half out and the characters could only attack it from the front. And they would have to move more than once to get to it, so it could get in a few attacks, maybe kill a few with a lightning bolt spell.
The bard was not going to have any of that, he rushed forth and inspired three of his allies that it was the time to finish off the the beast. He urged them to move faster and to attack true. The effect was that the three characters were able to rush forward two moves and attack! The ranger blasted the Naga with his bow, the Dwarf hewed it, and the paladin charged into battle again, the Druid ran across the ceiling and dropped down to bite the foe. The cleric blasted it with a spell and the Naga died.
The yuan-ti were not inactive. The two were fighting in the fight but they were just as surprised as the Naga was. They fired their bows and attacked with their weapons, but when the Naga fell, the one went to escape through the secret door, that was no longer secret and the other fought to cover its escape. But e characters were not having any of that two of them chased the fleeing foe and they caught it and killed it. Which spoiled a chance at having a recurring villain. Except it did not. Nagas are immortal, they come back. This Naga was a creation by an artifact, but that does not mean it can't come back, when it does the powers that it will have are less powerful, the charm won't last as long, but it will pursue them.
The characters gathered up the treasure that they could find and when they accomplished that, the temple complex began to fall apart and I forced them to use thier skills to dodge and weave through the collapsing mud pile in the swamp until they gained the entrance. The first person failed their athletics check and a section of the roof collapsed on her, the gnome that came to the dwarf's aid also failed and was sucked in to the mess getting them free, the next few rolls were blessedly high as they fought against the speed of the collapsing temple. The chance to explore the rest of the temple was no-longer an option they got out as it became a swirling mud pit. They had the treasure they found and they had the prisoners to take back to the Town. They might return to see if they can sort through the wreckage in hopes of recovering the remaining treasures.
They still have to get back to the town. They from there might head to Greysteel and hand in their ears. They might decide to tackle some of the other problems in the area. With them taking out a challenge level 8 monster with two challenge 3 aids, shows that they are more powerful than the game is designed for. They still have a lack of magical weapons. Which means some encounters are beyond their skills, but this will change. When they fought e Naga, most of their spells were depleted and they still won. The artifact they picked up is still a mystery, artifact fragment. The next fragment they find might just link up and create a thirst for more….
