Ceanus says that the Huns hate any Human (or near-Human) kind of celebration, and they suppressed the seasonal festivities while they were occupying Namnates. It goes along with their philosophy- they did not want the Humans honoring or thanking the gods any more than the bare minimum. They wanted all festivities to be oriented around how great and wonderful the Emperor and the Infernal Powers were. They didn't allow the traditional Winter Solstice tree, or the songs, dances, giving of gifts, etc. That is why this is so important to the people this year.
The group comes up with a rough map of the Corbilo-Namnates Area, showing the location of Savanacum, wedged uncomfortably between Corbilo, Namnates, and the Fey Forest.
From everyone's point of view, it is a bad thing. It puts a garrison of Orcs and whatever foul allies they have right in the middle of everything. No one will be safe, with them around. Hunters will have to be on their guard, travelers will not be able to safely travel on land between the towns, and the Fey will have to be very careful- which the Fey hate to do, because life is to be enjoyed, not constantly worried about.
On the other hand, it is clear that it is not a good thing for the Orcs there either. They are stuck far from allies, surrounded by those that they hate.
No, not a good situation from anyone's point of view.
