In the middle of summer a small town is beset by a blizzard that enshrouds it in a blanket of snow. The cause is unknown and all contact with the town is lost. The player characters are hired to investigate the town and put a stop to the blizzard if at all possible.
(An adventure written in the more rigid and hand holding "old school" style and quality level of original fantasy adventure modules from the early to mid 1980's)
A strange group of ghosts plague the grave yard, only seen under the light of the full moon and known to drive most men mad that hear their gibbering speech.
(A simple plug in side-quest with a twist, that is left a little generalized to fit in with any fantasy campaign with minimal prep work by a gm.)
A rather large armed group slowly walks the road. Unless you get to see what they transport, you could think it is a caravan with expensive goods, or the soldiers escort someone important. But this is a prisoner transport, on the way to mines, criminals on their way for punishment.
The soldiers may be willing to talk, the captain will have a few questions on you and the road, but they will keep distance, and part soon.
