Apologies! The answer is in Background, but I should have made it clear that it applies to Experience, as well.
"Backgrounds give players a starting Experience that can help them better use their ability. This can do a few things if roleplayed well. The most common is to replenish their Point Pool by the third dice that they roll. Other options include: minimize, shorten the duration of, or even negate a Consequence; allow for a reroll; allow for the change of 1 dice."
