Fahna's departure had no impact on the situation of Bothal Whatsoever. Her existence was nothing more than an annoyance for most people. A political disaster in the making.
So Fahna leaving by herself was good news to most of the parties involved.
Not to mention, this now gave them time to properly approach their true target, which was none other than Salvarez. The dwarf was considered to be a volatile bomb due to the unexpected accident his family faced.
Which if were to be found out by him, as well as the rest of the city. Things would go bad for real. There would be investigations by third parties and the truth will eventually be found out. Because no matter what day it is. Salvarez still belonged to the Bastard Bear bloodline, which was the closest to what might one consider royalty among the human kingdoms.
