NPCs and Perl

[Mrwalsh]

After some gentle perusing, I couldn't find anything that related to this, unless I completely missed it.

Here's the scenario:

Mob001 is standing at the Crushbone entrance. After a certain period of time (time being the only trigger), I need him to run down the path towards the throneroom, attacking orcs as he comes within their reach (which I think can be done with factions, correct?). Now, multiply the number of Mob001 to be about 10, to simulate a sort of "war", NPC vs NPC.

What would be the best way to go about doing this sort of thing?

Thanks ahead of time.
