Exploration with the campaign

I think I have finally found what the campaign is about with the merchants quarters (and the pit). Whenever you entre a new square, you explore. If the square is occupied you fight, then you explore. This is what the random fights are all about, since it would be dumb just to gather a bunch of empty squares and gain massive amounts of wyrd stone.
If you think about it it makes sense: Why would you search the ruins for wyrd stone only after a fight?

After reading through the rules some i noticed that looting (advanced rule III) takes place any time you are not engaged in a battle for a turn.

Also, are we using random warbands? if so we would have to be rolling whenever we take a new area that is unocupied. A roll of 1 on a d6 means a random warband is there and a battle ensues.

No random warbands since its a pain to organise and get someone to play the random warband.
