Your tribe was destroyed by a slaver raid. Only you managed to escape. Now, it's time to build up a new home.
Your faction will be a New Tribe.
Start with 1 persom.
Start with:
-Pemmican x100
-Herbal medicine x5
-1 Bolt-action rifle
This is basically the tribal start, but I changed it to the above. I simply like starting like this. The weapon is probably a bit much, however, this just represents this man/woman surviving a devastating attack on his/her village. His/Her tribe was wiped out by slavers, they killed the weak and took who they thought were the strong. He/she managed to escape with the items I've listed above. The rifles could have been salvaged from dead attackers, as a roleplaying explanation.
