Gm event help

[zosime]

HI all, i am new so far things been going pretty well. The server for most parts been stable for a few days.
I am planning on running a RP event with my close friends close to liek a book form RPG where gm narrates and looks over it all. So far everything is working, but one issue

For life of me I cannot figure out a way to set it up so that in game with a gm command i can summon several NPC to pop in the zone. Any of you know of any usefull links to help me with this?

second issue I would like to have is maybe some bots I can have with me as my henchmen t o order to attack the players. I donno if this is possible or not. Anyways any usefull links be much appreciated.
