This is the 3rd mission of the Voyage Home campaign.
Why would I need another hero? I already have 2, and besides, I'll buy a hero, but all the mines or artifacts are guarded by monsters, and the hero is weak!!!
In this mission, they play as Knights, not Barbarians (there's a hero named Gallavant).
As I already said, there are two heroes: the main hero, Lord Alberon, is stronger, and he will have either +1 skill or ranged attack, and the second hero, Gallavant, is weak, but he needs to be protected.
