FM Named Cycle

[Bulzie]

I read the wiki on this, see there are areas NW, SW, SE with mobs listed. But I don't understand the mechanics. So you go to SE and kill all the mobs in the list in that area and once u see no more up on track, u head to the 2nd spot, say SW and do same thing? Or is each area its own camp so as you clear the normal mobs say in the SE section, the named for that area might spawn?

I am interested in the Sarnak cycle.
