Your turn order in a conflict is based on your skills. In a physical conflict, compare your Notice skill to the other participants. In a mental conflict, compare your Empathy skill. Whoever has the highest gets to go first, and then everyone else in descending order.
If there’s a tie, compare a secondary or tertiary skill. For physical conflicts, that’s Athletics, then Physique. For mental conflicts, Rapport, then Will.
GMs, for a simple option, pick your most advantageous NPC to determine your place in the turn order, and let all your NPCs go at that time.
Cynere has a Notice of Good (+3), higher than everyone else, so she goes first.
Zird has a Notice of Average (+1), so he goes second.
Landon and Og both lack the Notice skill. Landon has Athletics at Good (+3), and Og has it at Fair (+2), so Landon goes third and Og goes last.
