Dark Ages

Wow. Who has nothing better to do than build a wall with those technologies?

Mostly – the Antams. See the description of the Erfu in the first message.

Lattern, is it behind the wall, as I understand?

Yes.
The penalty for trolls is ~ up to the wall, yes. And in the mountains (on the Bone Ridge, for example), there will be no penalty.

And is the Forge of Life also behind the wall (you mentioned the northwest)?

Yes.

And those who didn't have money initially, did they get it?

No, no one gets money. You either found it somewhere... It's up to you here.
Why I just "gave it out" – because the lack of money in a quest doesn't always mean that the player wants to play without money, so it's easier than figuring it out.

And what do these two hundred Ineys look like, are they coins or something?

Coins, yes. For internal use. Shaped copper coins with a hole in the middle. For trading with "foreigners," there are silver and gold equivalents (that is, whoever has silver or gold has 200 Ineys in these metals, which is 2 gold and 20 silver coins, respectively).

I think it's better to continue when there are strength and time.

Well, that means never, of course... Unfortunately.
