Hi guys i'm working on a large new questline with new NPCs, Bosses, Areas, Gear & Spells, i'm working on it at the moment but i'm having some real trouble, i cant find the full information i need on these topics, if anyone could point me in the right direction or better tell me from experience the best way to do these things with minimal errors i will really appreciate it.

Basically i want to recreate the Miraak intro situation, under certain conditions, you goto various locations and there are NPC's waiting to attack you, from there the questline starts, how do i do this? (Setting conditions for the players, that NPCs will be at certain map locations)

Next, how do i set conditions on which other NPC's will move to other locations on the map? (Setting conditions for NPC's to move to new locations)

And i mean globally, not in the same building dungeon city ect.

Appreciate any help guys thanks.
