NPC vs NPC

[Maceblade]

This may be stupid and im sorry, but simply im writing a script where I want NPC's to spawn and instantly start attacking one main NPC. Im trying to re-create the Capture of Kerafyrm and When all of Velious's named are spawned via event controller, I want them all to attack him. The part I need is the command where it tells the spawned to attack him and nothing or no one else.
