Skyrim – walkthrough and progression.

Then you'll have to look for new bandits...

I disagree; new bandits regularly appear in the place of those I defeated. For example, there are two towers with a bridge across the river (east of Waitran). I passed by there twice, and each time there was a gang there that I attacked.

You can get 20,000 gold for completing their quest chain, and another 10,000 for smaller tasks.

Money isn't a problem ;)

After completing it, you can take on endless quests, each of which gives you 1,000 gold.

The Companions also have endless quests.

The only downside is that you have to hide a lot.

I don't really like that; I didn't develop my hero in that direction. And in general, all these assassins and thieves... They should be cleared out, in theory. Can you tell me where to find the Dark Brotherhood's lair? :) Or do I have to kill that woman from the orphanage?

The College has the same thing.

Really? It seems like they don't give me anything like that. Or is it like cleaning the fountains?
