Interestingly, the same strat used by Coco.
Could I have the list of the 8 C1 Nalthians.
There is probably a way to solve this, especially with Qian's info-dump. The important info here is that Qian is the final-turned Coinshot who killed Star.
But if Qian has been camped on Sel, then the only way to shoot (non-Selish) Star would be by spending Investiture. But as Qian has been on Sel since C2, there is a very very small chance that Qian had any investiture at all. Investiture sent towards Sel never reaches the target because of Sel powers. The ONLY way this can happen is if TWO players target Qian and send them Investiture, they would then receive ONE charge. This is a massive waste of action economy and I do not think Qian had a charge to kill a non-Selish Star. But then, Star's randomised kill did not go through, which clearly means that Star was NOT on Sel and Qian was most definitely on Sel. The question is, how did Qian kill Star?
Where was Qian staying in C1?
