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.

(T.101): One of your parents was a lawyer. You will have proficiency in Persuasion.

(T.102): One of your parents was a merchant.

(T.2): You're the bastard! You have two brothers and two sisters.

(T.3): Your family is ensorcelled. A wizard offers to help remove the spell, but only if you help them out in exchange. Roll on Table 10.

(T.10): You accidentally break one of the wizard's magical trinkets, and the furious mage turns you into a toad. You spend a year living in a swamp before the spell wears off. In your original form, see if you can survive the swamp on Table 24.

(T.24): You stumble into a wondrous glade where you meet a fey creature. It touches your forehead, and you fall unconscious, but not before a single portent appears in your mind, roll on Table 32 to see what. Your life of adventure begins when you awoke far from this wondrous place with this new knowledge in mind.

    >>>> (T.32): You have only a handful of true friends.

Your age is TEENAGER
Teenagers are dexterious and hardy, and often are cocky enough to be quite assertive and convincing. Unfortunately, this does not translate into 'real' wisdom or intelligence, and a teenagers body still has some growth to do before they'll be at peak strength.
