The chief does indeed permit you to contribute to the workings of the settlement. So what can you do?
Help with the farming? Women’s work. Hunting? Only Antinor seems to have any skill at that, and even then he’s rather clumsy. Woodworking? No one has any decent skill at it, other than fashioning some weapons (spears, staves, and shields). Fashioning, repairing, and sharpening weapons seems to be where you’ll be most helpful. That and heavy lifting.
While a few elite tribesmen have metal weapons, you see no means to produce them. There are no smelts or anvils.
In various conversations that you pick up on, you notice that four distinct personalities seem to emerge: The hed-headed woman, who is known as the Tuathar; “The One”, a greatly revered giant; Alwynn, a highly revered mythical woodcrafter and healer; and the Giver of Life, which seems to be the Sun. All are held in high esteem.
It also seems that this is one tribe of the greater Taelda Nation.
A few things that you notice about Indwallys (the Tuathar): She seems to spend a lot of time alone, in what seems like a trance. She is often missing. Sometimes you catch her looking at you, then inscribing something on a clay tablet.
Some women bring you a beverage in elaborately carved wooden cups. It smells of honey, and you are told that it is a sort of health tonic.
