Midgard Lineages and Heritages, pg. 11
You grew up on the Crossroads of a trade hub. Those raised here value two things above all else: commerce and freedom. Those of this heritage work to improve their own lives by their own means. Almost everyone plies some sort of trade to take advantage of the trade routes that cross through here.
Growing up in one of its varied districts breeds a shrewd mind for business and a defiant spirit of independence. Regardless of whether you spent your days in the high halls of the Collegium or in the slums of the Kobold Ghetto, you know the best way to earn a better life for yourself is to do just that: work for it and earn it.

Defiant
When you fail an INT, WIS, or CHA save, you can reroll. You must take the next result. Once you use this feature, you cannot do so again until you finish a short or long rest.
