Actually, he is one of the few vanilla independent that travels. (that summons that creates "the Hunt"? that Captain that hits random coastlines? isnt there also a summoned demon group that moves on its own?)
But, if you turn on Special Monsters 23 and 24 as computer players
chaos_unites.map: #computerplayer 24 4
chaos_unites.map: #computerplayer 23 4
you get a very interesting effect of more active independents. I use it in my Chaos games.

Those two commands added to a map on a game server creates a castle, god, scales, etc for "nations" 23 and 24. Its not any smarter than the usual AI (unless you take further steps to boost it) but its fun because both nations have a slightly different AI and they both use the white banner of independents. WARNING: now its not just the other nations. The Independents are also trying to unite against you!
All of a sudden, the indept province next to you has a drastic army change and is now made up of a variety of indept poptypes (one of the SpecMon AIs has captured the province). And the indepts next door suddenly attack your province. Trying to track them back to their castle is not as simple as just following the flags. You dont know which of the indept provinces around you are the old stand-alone or the new mobile version. They buy mercs also.
As an added thing I like to ally them. So in the Chaos games you can have 1-4 human players (allied or not), 3 AI nations (allied to each other), and 3 versions of Independents (with the two Indept AIs allied to each other).
Of course since these are CHAOS games, there is the added fun that every province, including the indepts, get random units. So these surprise Indept armies can include pretender forms, angels, demons, horrors. etc. But some might just want the indept AIs for fun.
NOTE: its about time for another re-work of the games on the server so the Chaos games may see changes in size, maps, and surprises.
