In her few years as Recon moving meanderingly west, Dora has learned that every settlement has its stories of monsters. The boogeymen and baba yaga in the wilderness kidnapping children, the demon-run hostels in the wilderness that serve human flesh before grabbing you for the next meal, the great predators that roam the wastes and whose coming is foretold by earthquakes, and so on.Dora the Red, what is the most dangerous thing to those wandering the flats? What is the thing you're most worried about heading from the flats into the community?
In her actual experience, though, it is humanity that poses the greatest danger to civilization. The Lorekeepers in the eastern bases recite the tales that humanity had once controlled this world, bending fauna and flora to its will and trading goods across the entire surface. It was humanity's base desires and penchant for barbarity that brought down its own dominion of the world.
The raiding clans that strike caravans heading across the flats are what she feels are the greatest danger in the flats. They break down communication among peoples already too tense, increase the division between civilizations that should work together to survive and become greater, steal goods that are meant for the hands of others. They break down what needs to be strengthened.
Dora is somewhat worried about the influx from the Babylon, though mainly because she rather likes Ehrenschild. To her knowledge, the Division cares little about what kind of civilization they protect, as long as it ensures "basic human dignity". Though that is a relatively fuzzy term, she feels that Ehrenschild's rules suffice and is a little more wary of the Babylon people's promises.
Her primary concern, though, is reserved for those that would come in to break Ehrenschild's peace. Dora allows herself little access to Ehrenschild's part of the community ("Do no violence or intentional harm" being a sticking point for her, as a relatively self-aware and honest person of extreme violence) and is concerned about those that would intentionally seek to break her rules to diminish or overthrow her power.
