This tool is based on the work of user Arachobia on RPG Crossing with his permission. He had taken a list of tables from Dragon magazine #422 in an article called "Building Character" by Matt Sernett and updated them for 5th edition. I've turned them into an automatic tool for generating a characters background.

Instructions: Refresh the page to generate a new background story. As always, you can use it however you like and fill in your own details. Your age and acquired proficiencies are listed at the bottom and are based on the results you got. Try to pick a Race/Class/Background combo that fulfills all the proficiencies. Your age may also result in ability score modifiers that can be applied after building your character.

...or ignore everything and do whatever you want. Whatever.
Background Generator

(T.101): One of your parents was a great hero.

(T.102): One of your parents was a diplomat. You will have proficiency in Persuasion.

(T.2): Two stepsisters.

(T.3): What better way to see the world then with a caravan? Roll on Table 20.

(T.20): The earth shakes as a Bulette appears and begins to destroy the caravan. You fall through a crevasse opened up by the beast and tumble down to Table 25.

(T.25): You wander in dark caverns for who knows how long, subsisting on insects, bats and whatever else you can catch. It's a miserable existence: roll on Table 31 with a -5 penalty to see how it affects you. Then re-roll on this table.

    >>>> (T.31): You find this 'hardship' almost trivial and come out of it even stronger than before. You will have proficiency in Survival and Athletics.

(T.25): Beneath the earth, you discover a huge statue with ruby eyes. You pry one lose, but then are forced to flee when a tribe of goblins chases you out of the tunnels. On the bright side, they chase you back to the surface where you sell the ruby for a tidy profit. You will have +50% starting gold. On the downside, it turns out the ruby cursed you. Roll on Table 7.

(T.7): You were cursed with a kiss that nauseates and chills any who lock lips with you. You need to find a person to lift this affliction on Table 11.

(T.11): You discover you need more information to find what you seek. You will have proficiency in Investigation. Roll on this table again, but regardless of what you were searching for originally, you now are seeking information.

(T.11): You turn up nothing. Your life of adventure begins with no progress made in this search.
