From the publisher:
Why hex crawls?
The answer to this is very simple. It is widely accepted and even mentioned in the Dungeon Master’s Guide that our favourite RPG has three pillars – combat, roleplay, and EXPLORATION. However, the exploration system for at least 5th edition is largely ignored.
It is my belief that the fantasy of being Marco Polo or David Livingstone, is a strong and distinct fantasy. Also, think of Star Trek – to boldly go where no one has gone before; or Indiana Jones travelling through strange jungles to find lost relics. The fantasy of being an explorer is vibrant and ever fascinating.
The best way to simulate the stories and movies we have consumed, where we go through strange new lands, where every new mile brings new surprise; is by exploring an unknown part of the gamemaster’s world hex by hex where every new hex brings new surprise.
