"What you people need are air condensers" she says with a nod, pointing at the respiratory device over her mouth and nose. "Right now you stand out as foreigners in these suits. Follow me!"
Trinia takes the lead and guides your group through alleys and less crowded pathways, avoiding open space as much as she can. You can't help but notice that the symmetrical way in which the city has been built provides precious few of those and were it not for a full-on riot drawing the attention away from you, navigating this place undetected would have been much harder. Eventually, she gets to a wall decorated with a beautiful tiled mural and presses some sort of hidden switch that opens up a trapdoor on the ground, inviting you in with her. It's an uncomfortable crawl for a few moments, especially doing it in the hazmat suits, but once on the other side, you find yourselves in some sort of storeroom with all kinds of supplies randomly thrown about, the mess a stark contrast to the strict symmetry you've been witnessing all this time. Trinia digs through the heaps of items and pulls out a few respiration devices like the one she has on and passes them to you, when another person joins you through some kind of different hidden entrance on the wall to your right. A man in, you presume, his mid 30s, dressed in practical clothing that's still kept in great condition, complete with his own respiration device.
"Who are you... aw, damn it, Trinia, what have you gotten yourself into this time?"
