Historical Context Edit
Her pseudonym was inspired by her family motto "Deo, non-fortuna" (Latin for "by God, not fate").
How to Unlock Edit
Official Hint: Abandon everything.
You must be on Expedition 4 or later, hold a Standing of 8+, and stay overnight in a native village. Eventually, an option will appear that allows you to stay with them forever. The chance of this event occurring increases the higher the player's standing is.
Once the prompt arrives, accept it. Your game will be over, you will not be scored, and the explorer you used will not receive a statue, nor unlock any frames. Instead, you will unlock the Dion Fortune character.
