This one will take a bit of patience, not least because you will most likely need to find a partner who is fertile if you’re a male, or just hope that you’re fertile! Needless to say, you’ll have a better chance of achieving this one if you start your campaign with a character in their early 20s, rather than an older one. Note that the children will only count to a total for each individual character, so you can’t rely on your descendant’s children contributing towards the count.
