I've got both letters has anyone tried to give the mook both letters?

and if I steal the "item" from the mook can I show it to both the trang and the umpani.

You can give him both, I always do that. You only need to show the chaos moliri to the Trangs, Yamir just wants an letter from the mook. The mook handle the second letter like the first, they don't care, if they are already alligned to anybody

Either letter will get you in the door, and from there the process of switching the CM for the AD[fake] is identicle.

When you 'give' the CM to Z'ant, he tells you to keep it for safety.

Don't think the Umpani want to see it, but if they do, they too tell you to keep it.

Umps more interested in an alliance with the mook, and want the agreement letter the mook will provide you.

HTH,

Oru
