spawning mobs for the players

[eski2]

I'm trying to set up a sample spawn group of arboreals. I have the npc ids and use #dbspawn 540xxx to create the right type. However, i thought that they'd automatically start wandering like the others in Greater Fay.

Are paths set for every mob or can they just walk randomly?

Is #spawnfix required to save the spawn points?

What would you do to make killing them raise plane of growth faction? I can vaguely understand how to edit the factions but can't wrap my head around what to do for this sort of problem :P

If i was good at graphics, i'd love to make them appear more undead, assuming editing the models they use is even possible.
