This journey is perilous, but those who survive will be rewarded beyond the scope of the imagination.

For your journey, you will need many men. 

You will need:

 someone who comes from a large family, primarily women;

 the spoiled son of a rich nobleman, who is unimpressed with the success of others;

 a laborer who does not meddle in the affairs of others;

 a great warrior, the greatest you have ever known;

a man with many young children and long hours at work;

a brave woman with no family to miss her;

and most importantly, you will need a mute. 

You may have as many extra men as you think you will need, but these are the essentials. 

You will fail without them.
