There are many laws in effect in Forgotten Kingdoms. Some depend on where
you find yourself in your travels, but some actions (murder for example) are
outlawed in most of the kingdoms.
Please note...mobs are people too when it comes to being victims of a crime.
You can be outlawed as easily for attacking one of them as any player
character.
The most common crimes which people are convicted of are attempted theft
and theft, attempted murder, and murder. Each city across the has its own
law system and its own law-keepers. Some are far harsher than others
when it comes to punishment or leniency.
Waterdeep soldiers for instance jails thieves and murderers. Zhentil
Keep guards aren't as vigilant.
The shopkeepers in Waterdeep are protected, and killing them or attacking
them is considered against the laws of Waterdeep. Other towns have similar
rules. Those caught stealing from these shopkeepers will be incarcerated
by the guards Waterdeep until such time as their release is granted by the
gods.
