Age
Source Player Core pg. 25
Decide your character’s age and note it on the third page of the character sheet. You can play a character of whatever age you like. There aren’t any mechanical adjustments to your character for being older, but you might want to take it into account when considering your starting attribute modifiers and future advancement. Particularly young characters can change the tone of some of the game’s threats, so it’s recommended that characters are at least young adults.
