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.)
Swordbiters are parasites. They are long, thin and silver, and digest metal, somewhat like rust monsters, but smaller and more insidious. They resemble stick insects, but when they cling to metal they are very well camouflaged, and one can be biting your sword for a week before you notice it. They cannot be removed by hand, as they are very strong, but if the blade is inserted into fire they will leap off to escape the flames. Sometimes, old treasure hoards are infested with them, and the first glimpse you get of the "glittering" weapons is a pile of rusted swords encrusted with these thin silvery insects.
