maybe it will be clearer after the maps are available

What are the possible organizational structures:
1) Mercenaries taking on any combat contracts – standard.
2) An organization pursuing its own goals (and contracts are just a side activity, or a means to an end). Goals: power (creating a certain semi-legal network to increase influence), strength (to become the most powerful fighters, who must be reckoned with), something more plot-driven (searching for a specific artifact or artifacts in general), maximizing fun, sowing chaos, or other options.
3) An organization protecting the interests of another group (a state or a specific political force within the state).
4) Something like the League – simply providing free assistance to everyone, a kind of forceful charity. This option is, of course, difficult – it will be problematic to exist without finding a sponsor.
I can't think of anything else right now.
