Probably less useful than I first thought for the Society of Thule as detailed in the book given that they are armed either with a pistol or sword as opposed to a Rifle.
I've been playing around with the IHMN rules for companies a bit more after my Tong gang didn't seem to have lots of rabble...
Cheapest figures so far seem to be:
3 pts - Cultist (Club) - Servant of Ra
6 pts - Anarchist (club) - Brick Lane Commune
8 Pts - Native Bearer (Spear and shield) - The Explorer's club
The Servants of Ra and Explorer's club have got enough high value personalites to easily use up points, so the likely largest faction, miniatures wise, would currently appear to be the Brick Lane Commune as their personalities are relatively cheap by comparison. Even then the Anarchist can be made fearless, or given a knife or shotgun upping their points. Otherwise, the basic footsoldier would seem to be in the region of 18-22 points for most factions.
