Nastassja is the tech expert behind Maria's team, though she's basically the heretical one of the bunch—which means she knows way more about the holy relics than she probably should. Most people only got wind of that stuff after the Luna Attack leaked it, but Nastassja's knowledge goes deeper. She swings between being genuinely supportive of Maria and the crew to being brutally tough on them when the mission demands it. Fans often note her hot-and-cold approach, though it's clear everything she does is in service of what they're trying to accomplish.
