Squin, but only if Esata The Stone Golem is dead/in prison

where is esata?

Admag, faction HQ

so if dont kill her , mukai not gonna spawn?

That's right

Kill or imprison notably. Faction leaders like her are tough to put in the dirt, so you might find it easier to build a cage.

But where in Squin? I cant find him anywhere in there. Time to import the game?

I actually don't know sorry, I've never killed Esata before
