Nemo was only mildly interested in the nobles who showed up for the parade, of course, they had polished their faces and powdered their armor; it was all just for show. Moreover, it wasn't even interesting, but incredibly boring. The peasants' shouts didn't add to the spectacle; they just grated on her ears. Instead, she stood aside and once again checked the legend she had created in her mind. After making sure she hadn't forgotten anything, Nemo shielded her mind from outside interference and, just in case, changed her appearance to match the legend. After that, she immediately went to fill out some paperwork; this would ensure she had at least some money.
On-site, she registered for the expedition as Mark Schiller, a young, experimental mage who had likely suffered incurable burns during an experiment but had also gained incredible strength and endurance as a result. Mark was signing up for the expedition because his laboratory had burned down, and he had no intention of remaining a disfigured wretch for the rest of his days; he wanted to find a way to heal himself. And for that, he needed money, and a lot of it. While filling out the paperwork, Nemo casually, but deliberately, showed off a patch of "burned" skin, only to immediately cover it up shyly.
It depends on whether you're looking for the Grail, like I am.
