Wandering NPC

[Neiv]

Does anyone have a quest script that could act as the basis for an idea I have? I would like a certain key npc, who has a valuable item, to “wander” randomly from zone to zone such that players who are in need of this item could not predict where he will be next and much actively search for him. I assume this would entail a global quest that depops the npc from one zone (based on a timer) and simultaneously spawns him in another. I can envision many directions I could take in this, but I'm not confident they are the most efficient.
