Room One: Entrance and Guardian
They meet a small child upon the road near sunset. She is perhaps 9 years old wearing a burlap sack as clothes and her face is darkened in the growing shadows of the setting sun behind her. As they get close enough to make out features they see obvious signs of a rash and purple spots covering her exposed body. She is walking in a trance and doesn’t acknowledge anybody.
If anybody tries to heal her, whether physical or spell, her eyes will dilate as she looks towards the now visible moon, her arms will swing parallel with the ground and a otherworldly wind will blow her hair and clothes in a dramatic way as she recites the following:
Of the fifth the fourth the third
Alight the skies will the birds in flight
Follow it you may
Follow it you might
You must choose to go
You must choose to do right
The child will then slump and pass away peacefully. About a minute after she dies a deep exhale will leave her body and a black mist will roll from her mouth and swirl towards the forest. It is quickly out of site in the darkness.
The players may do whatever to the body, it doesnt do anything else.
Room Two: Puzzle or Roleplaying Challenge
Once they continue on they will soon see a wagon off the road with two horses still hitched to it. When they investigate they will find two adults that have the same disease the child had. They are slumped in their seats as if they both died simultaneously and just slumped over. Searching the wagon they will find little of use but they will discover some small articles that would belong to a small child.
As they are investigating a flock of birds will be disturbed not too far in the forest and fly directly overhead. As they look up to follow the trail of birds they will see a faint glow in the low clouds as if emanating from something deeper in the woods.
The light is coming out of the top of a mound. If they go to the top it is a circular rock that is throwing the light upwards. If any of this group touch it, it instantly goes out and a portion of the ground sinks in the shape of a square. They must dig to reveal the door.
On the door, once cleaned, will be eight runes. If anybody can read them they are:
anger death sadness hope life happiness love fate
From what was recited by the child they should choose life hope sadness and the door will open.
1. There could be others at the site already. The glow may have attracted those within site of it. They may have to fight their way through them. Some may be diseased people looking for a sign. As they will see, actions against these people may have negative effects later on.
2. The person that attempted to heal the child must be the one to do all the tasks or magical traps would be set off.
3. The runes must be chosen in the correct order or magical traps could be set off.
Room Three: Trick or Setback
As they start exploring the series of rooms one of the players finds that they are getting a rash that really itches. As they continue it starts to bruise and perhaps bleed and is getting painful. No healing does anything to it.
The kind of cave system doesn’t matter. Could be natural, man made, a labyrinth, whatever but it should just take enough time for the symptoms described to start taking good effect. If they try and go back out the way they came the exit is closed and impossible to open.
Room Four: Climax, Big Battle, or Conflict
They will begin to hear a lot of shuffling and groaning echoing down the passageway. They will see a light at the end of the current passageway and shadowy forms passing back and forth in front of it. None moving quick, a shuffling limping movement. The corridor opens into a huge open room with a ceiling that goes beyond the light. The light source seems to be coming from something at the other end.
The moving shadows are men, women, and children at the last stages of the illness that they watched the child die of and the same symptoms that the one player is developing rapidly. None of the people are carrying weapons, but as soon as the players enter the room the nearest plague victims pivot awkwardly and start walking towards them with arms outstretched. The wounds are dripping and livid with puss dripping from them. It would seem any contact from them would get this liquid on them.
If they resist purposely hurting anybody as the move towards the glow they will find a goblet of liquid.
If they fight their way through or hurt anybody maliciously they will meet the black mist that saw come out of the girls mouth. It will question them on their intentions and why they would hurt defenseless people. If they answer good enough or show regret at their actions, the shadow spirit will allow them to continue to the goblet. Else the spirit and the people in the room will disappear and they will have to return to the entrance that is now open. They will have to deal with the disease as the DM sees fit.
Room Five: Reward, Revelation, Plot Twist
The goblet of liquid can be drunk by anybody. If drank by the person with the growing disease then he can watch as the disease disappears and he returns to normal. They may offer the drink to those in the cave but they will also find that anybody who drinks from the goblet has a healing touch for the next 2 minutes. Anybody they touch retains the healing power for 1 minute. Once any of the diseased figures in there drinks or is touched, they touch the next one behind them and they spin into a golden mist and disappear into the darkness above. The room will be empty within moments with a sparkling display of golden, lighted mist flying into the darkness.
The dark shadow at some point will tell them that the goblet will work as long as the players seek no personal gain, heal for selfless reasons, and do not allow anybody know they have it unless they decide to turn it over to another person who will fall under the same rules. If at any point they are selfish, sell the healing power, or if somebody catches them using it the goblet will turn into a useless tin cup.
The goblet never empties (you cant just pour it out though, that will empty it and the poured liquid acts as normal water) and they are able to remove it from the tunnels. They will leave the same way they entered.
The plague can then be used as a tool of the DM as they wish.
