27 years ago - 18-year-old Inza begins studying archaeology.
23 years ago - 22-year-old Inza begins her graduate work in anthropology and comparative mythology.
19 years ago - 26-year-old Inza begins her doctorate work studying the lords of order & chaos.
17 years ago - 28-year-old Inza discovers Fate's Tower & convinces Kent Nelson to take her on as an apprentice & assistant. while inside the tower, her aging stops.
5 years ago - 28-year-old Inza comes under the influence of T'Giian's Amulet & leaves Fate's Tower. She joins the Justice League as a new Doctor Fate, her location hidden from Kent Nelson by T'Giian.
4 years ago - 29-year-old Inza is overwhelmed by her amulet. The Justice League find Kent Nelson in Fate's Tower. He battles Inza, saving her from T'Giian. They are married by Nabu, & return to the tower.
Inza Nelson suffered from something we're taking to calling the Sue Storm Effect; a female character who would make perfect sense if they were written as an equal to their husband/male counterpart, but the men writing them were unable to do that, and so they came across useless. What's worse, because the character is left with no purpose and nothing to do and is totally subservient to their male counterpart, they wind up resenting him.
Meanwhile, the female Doctor Fate that joined the Justice League was Linda Strauss, who shared the role as Nabu's host with her son Eric. Imagine the most uncomfortable version of that story you can think of, because that's the one they used. We'll be skipping that altogether.
Our version of Inza is an anthropologist who's research led her to study the lords of order & chaos, which leads her to Kent. She's proactive. She chooses to stay with Kent as a student, chooses to learn the magics of Fate.
That last part might be the most important change. Being Doctor Fate is no longer something that can be passed willy-nilly between hosts. Kent and Inza have studied and earned the role.
The notion that her rebellion from Kent is born of her corruption by T'Giian, the lord of Chaos, creates a new story that we get to see play out among the Justice League.
