The first character has a huge impact. Let's say it's a scout. The scout's initial exploration and discovery can drive the narrative in a direction of mystery and anticipation. Their findings might lead to new objectives or uncover hidden threats. They can also be the eyes of the player or reader, making the world of the war story seem more immersive as they report what they see and experience.
The first character is like the key that unlocks the story. If it's a fearless leader type, the narrative might focus on strategic decision - making from the start. For example, they could lead a charge or plan a defense, which then sets the stage for the rest of the story's events.
Well, if the first character is a deserter, for instance. This completely changes the tone of the narrative. It starts with a sense of conflict not just against the enemy but also within the character's own moral compass. The story then might revolve around their journey to redemption or their reasons for deserting, which can be a very different kind of war story compared to one that starts with a more traditional heroic character.
