Not sure to be honest - ages ago shortly after 1648's release. But knowing me I would guess it was script, I did the screen shot as proof of concept for the banner symbols.
Edit: must have been descr_strat. I used the following code for these fresh spawns (top row descr_strat, bottom row script):
descr_strat, slave faction's section - note that omission of sub faction was acceptable, banner symbol reverted to culture of region's owner (moors - ME) in that case. Anyone noticed the different directions the armies face? strat=straight, script=left
Code:
character random name, general, male, age 26, x 102, y 43
army
unit Spear Militia exp 0 armour 0 weapon_lvl 0
character sub_faction england, random name, general, male, age 26, x 104, y 43
army
unit Spear Militia exp 0 armour 0 weapon_lvl 0
character sub_faction sicily, random name, general, male, age 26, x 106, y 43
army
unit Spear Militia exp 0 armour 0 weapon_lvl 0
script - all armies use the banner symbol based on the region owner's culture. Brigand spawns do the same.
Code:
monitor_event FactionTurnStart FactionIsLocal
spawn_army
faction slave
character random_name, general, age 30, x 102, y 41
unit Mongol Bodyguard exp 6 armour 0 weapon_lvl 0
end
spawn_army
faction slave, sub_faction england
character random_name, general, age 30, x 104, y 41
unit Mongol Bodyguard exp 6 armour 0 weapon_lvl 0
end
spawn_army
faction slave, sub_faction sicily
character random_name, general, age 30, x 106, y 41
unit Mongol Bodyguard exp 6 armour 0 weapon_lvl 0
end
end_monitor
Note: I changed the sub_faction entries to hre and scotland respectively in both codes - it only effected a change in accent with the descr_strat entry (given the previous observation rather obviously).
Should the region be owned by the slaves then the 'creator' entry defines the banner symbol used, see the settlements and slave army below, Breslau is Polish\EE, rest is German\NE:
