Well frist I want to create a NPC who trade ONLY with members of the clan who own a castle, i have the HTML and XML ready but i dont know how to set this

Is there any way to make some NPCs dissapear during Sieges? or make them unavaliable for anybody (like guard who give the attackers and defenders info)

And finally, i want to create a NPC who spawns every X mins in many locations, like Merchant of Mammon does...


Any help with this issues will be greatly appreciated

about the random spawning, i think there was a table in database for that, like npcid, loc1, loc2, respawntime, or at least that's how i would imagine it
about the specific-players-only npc, check that very same guard html, if there is nothing there, than probably it's done in core
if such things exist in server already, you just need to find them and fit them to your needs, i'd say you're lazy...
