Dungeon Crawl Classics
An old farmer. He's dead when the adventure begins.
As a young man, Roberts saw a portal to another world one night. He went out of curiosity and saw gold and fine weapons and armor, but he was too afraid when he saw the monsters and mechanical men. He ran away and missed the chance of a lifetime.
As an old man, his biggest regret was not taking the chance when he had. Now the stars are right again. The empty star constellation, which hasn’t been seen in 50 years, is in the sky again. He remembered where the portal was and implored the adventurers to take the chance he never did.
And so began their adventure. For good or for ill, he set them on the course which would change their lives.
