Your group is asked for help escorting an inebriated priestess back to her nunnery before dawn.
Start off your group is on its way to the village when they encounter a short elf and a elderly mage trying to carry an unconscious woman dressed in armour.
Encountering them the wizard attempts to bluff his way past them, but the elf openly asks for their help.
"The priestess Aneela had conned his help for a meeting with a visiting mage"
The wizard attempts to butt in but is clearly embarassed and seemingly drunk himself.
"I think she charmed him and got herself charmed by the visitor who called himself Barnabus Glare though his goblins henchmen called him Bargle..."
"Anyway I had to deal with the goblins as Barney led her inside and we pursued them and the other mage ordered her to attack us. I employed a gas pellet that knocked her out and he caught enough to as you can see still look like he's drunk," he sheepishly shrugs.
"Could you escort both of them back to the monastery, they should pay you for your trouble.
I can't as I need to double back to make sure they didn't send anyone after us,"he asks.
The trick isn't the trip to the monastery which is next to the village they're travelling to its just that they will run into guards who will help them with that, but will be asked to stay overnight whilst they check on the pair they're escorting.
Next morning they're asked to investigate where this meeting took place to see if they can confirm what was done to the pair as the elf has conveniently doesn't want to explain himself.
So they could either go after the elf, remembering where they met ask any of the monks about the local quickly learning of the ruin atop the hill which is the only complex suhc a meeting could take place.
Now remember the 80's red box solo adventure?
Run that for them with the goal of discovering the complex is a goblin base under the control of the Dark Knight and Bargle is his vizier.
The priestess charmed the wizard intending to use him as a sacrifice to join the Dark Knight, but the elf's interference caused the Vizier to charm her disrupting her own attempt to charm him causing her to pass out when the elf threw his gas pellet at her which was just a flour based bomb and wrongly assumed he did something wrong so got them to the monastery as fast as possible.
By the time they return the priestess has awakened and fled the monastery, the wizard is still grumpy and the elf still refusing to go to the monastery although if they get into trouble he will help them out but is a rookie like them.
Hope that helps even if only to inspire you of something of your own!
