Mountains can be rather dangerous places, filled with all sorts of creatures, natural hazards, and harsh weather conditions... Sounds like just a place you'd find yourselves as an adventuring party. And Off the Beaten Path is here to help any GM whose players decided to not heed the warning and go into the mountains anyway. The book of mini-adventures is up on Kickstarter now.
From the campaign:
A minimum of twenty single or double page mountain excursions to use as side quests or stand-alone adventures for your Fantasy RPG. There are over twenty-six pages of encounters found within cold mountain passes and snowy locales. As your player's characters travel through the frozen wasteland, they will come across tombs, yeti caves, snow drake lairs, deserted lodges, and more! These adventures are a great way to add additional encounters during travel, or to handle an unexpected change in direction!
The campaign's up and over its funding goal, but there's only 7 days left if you want to join in.
