The Avengers first met Nyx after the Battle of New York. She just… appeared. Judged. But helped them. And since then, she just stuck around. Always there. And when she wasn’t there? She’d materialize out of shadows. Nobody had any idea why she was there. But she was. But that was until Civil War. She was conveniently absent during the debates. But she just appeared on the terminal during the battle. And her expression? Disappointment. And something worse. Like she was watching a tragedy start. She wasn’t taking any side. Just watching them with that look. Not even speaking to them. Not even commenting. Just watching and helping sometimes with things like dissolving concrete into shadows or stopping fires with darkness.
