I wanted to include Zavala, Cayde, and Ikora in the timeline, but it's unclear when they joined the Vanguard, except for Zavala who became the Titan Vanguard either just before or immediately following the Battle of Twilight Gap. Saint-14 defended the city at some point before the founding of the Vanguard, but it is entirely unclear how or what against. (I assume the Fallen) Alpha Lupi is a grey area. Jarren Ward really only tells the story of The Last Word.
