Immigrants could vary in inventory - they could be equipped or lacking any of: clothes, tools, food, or even weapons.
Also they could come occasionally with children (refuge families).
It could be up to player’s choice to accept them, depending on the situation.
Some “lore” ideas:
- Refugee noble family - full clothes, full of long term food, adolescent children
- Poor farmer family - some clothes, new born babies
- Army deserter - weapon, armor
- Craftsman refugee - full clothes and tools
- Prison escapee - empty inventory or some random stolen stuff
etc.
