>Your PCs are a team of couriers and mail-carriers tasked with delivering supplies and communications between remote mining and fishing communities in the frozen northlands.
>Together, you crew a large crawler vehicle, designed to haul cargo through the snow and provide comfortable if cramped shelter for its operators as they make their appointed rounds.
>As the government's presence and ability to respond to incidents and accidents in this region is tenuous at best, the PCs are often asked to help with a wide range of situations.
>Most of these are mundane in nature, like delivering a time-sensitive letter to the next town along their route, checking in on an elderly prospector or repairing a faulty generator.
>Sometimes though, the situation is more creepy, like running across a "cursed" unfinished rail line, like investigating mysterious disappearances or sighting otherworldly creatures.
What are some potential cozy or creepy quest hooks, happenings and set-pieces for the crew of a roving snow-crawler to come across as they traverse the great white north?
