Aria has wiped out 2 different Thieves Guild branches in 2 different cities, and the second one was the one and only Thieves Guild branch that specialised in combat.
Most Thieves Guild members have skills related to stealth, lockpicking, blackmailing and the like but avoid violent crimes beyond...
It is only on reading your comment that I realise it is probably a cut-off final and not some kind of NAL exam (no idea what NAL could have stood for).
I'm pretty sure that if Rina said that another country had a delicious ingredient (chocolate for example) then that country would be very quickly added to the empire.
It feels like there are pages missing?
It suddenly went from the cursed mask about to be put on to Cry leisurely playing with illusionary dolls.
Or maybe the continuation of the cursed mask will be in the next chapter though.
Could be a mini-flashback to what happened after it was put on Tino.
