Here's a fact: we don't know much about the Gurriki, given that they only live here in Tiamaranta.
However, they're just as likely to be territorial or outright working for the Balaur as any other Sapien.
Kahrun's Will weakening in their lands means that Tiamat is probably planning something serious for that region. Whatever it is, it must be stopped.
Kill [%dic:STR_DIC_M_LDF4b_C1_GururuFi_57_Ae]s, [%dic:STR_DIC_M_LDF4b_C1_Gururuwi_57_Ae]s, [%dic:STR_DIC_M_LDF4b_C1_GururuAs_57_Ae]s, and [%dic:STR_DIC_M_LDF4b_C1_GururuCl_57_Ae]s; fewer hostile Gurriki should mean less chance of any plot working.
Personally, I'm not sure Tiamat's done us any favors by weakening Kahrun's Will.
The Reians are right about one thing: having to fight the Asmodians certainly does leave us less able to fight the Balaur.
Hopefully, keeping the hostile Gurriki in check will keep some of the pressure off.
Good, good. I'll report to Ancanus that our schedule is proceeding on time.
The friendly Gurriki have been approaching us, asking for aid in swaying their bretheren. Perhaps your efforts will contribute to that.
Thank you for showing everyone that allying with the Balaur only brings one reward: death.
Defeat [%dic:STR_DIC_E_Q12063All]s in the Gurriki Grotto ([%2]/10).
Report back to [%dic:STR_DIC_N_Karuti].
Kill Gurriki Fighters, Gurriki Sorcerers, Gurriki Sentinels, and Gurriki Healers, who may be part of a larger plan by Tiamat.
Karuti expressed concern that Tiamat could be signalling interest in the hostile Gurriki of Gurriki Grotto.
Thus you fought the rogue Gurriki, leaving Tiamat with fewer resources to work with.
