(97). Whenever your player characters are in a city, always expect them to cause a motherload of trouble for everyone just for the fun of it, usually beginning at the tavern.

(99). It is a good idea to have an NPC accompanying the PCs at all times. This way you can communicate to the players whenever you want, through that NPC. But make sure that NPC is at least somewhat knowledgeable and can hold their own in a fight, otherwise the players won't respect him or her at all. Oh, and make sure that NPC is a male character, otherwise that NPC will get cop and feeled by the most perverted and least-self-controlled member of the group.
