Gameplay Setup: This one is a bit complicated, so please bear with me. At this stage, the player controls Luna traversing the 4X map. Once Luna has routed three legions of troops on either side, the war is over. Alternatively, she may collect enough Souls to advance the story with neither side fully winning. The map looks like this...

Narrative Setup: In order to save the Deadrealm, humans in the Kingdom must start dying. Natural causes are not doing the trick lately, so Luna plays an active role in stirring war between the fiefdoms of the Deadrealm-hating Lord Branwarden or the overall detestable Sir Neew. The question is, will she choose sides or go her own way? That's the player's decision...

This is not necessarily a choice, as Luna can do both because three legions need to be routed on either side:
Confront Lord Branwarden's Troops
Confront Sir Neew's Troops
