Certainly, I imagine actually watching several people brutally killed in combat would have some mental impact on those that survived. Play it up.
Also, it may feel like weeks of game time but in reality it is only the fourth day since the campaign began. I have built a calendar in excel where I keep track of what takes place on which day.
The FR calendar is broken into 12 months and has 5 (sometimes 6) special holidays called out. Each month has 3 weeks called Ride and each ride has 10 days. There is no special naming for the days of the week, they are commonly referred to a s One-day, Two-day, Three-day.
The current date is Six-day of the First Ride of Eleasis (the month is also known as Highsun, like August on our calender). The midsummer festival referred to in the player handout was seven days ago. The Shieldmeet (like our leap day every four years) was the day after that.
The local holiday celebrating the last victory of the Red Fist armies is near, known as the Heroes of Delimbyr Vale day or Hero Day for short. It is on One-day of the Second Ride of Eleasis, so 5 days away.
