[SixOfSpades]

As a rooty-tooty, Awfully Lawfully Good Plooty Paladin-Piper, I have observed the following tenets:

• Enter every building. My travels in the city of Baldur's Gate have taught me that Evil can be found in even the most innocuous of places, and what good is ridding the countryside of monsters when insidious vice spreads beneath our very feet?
• In the course of pursuing Point 1, explore every area (if the building is multistory), and kill all monsters. Talk to all citizens--being slightly touchy with those who failed their Detect Evil, and very polite to the rest. ALWAYS obey an implied command to leave the person's home.
• If no residents are at home, feel free to examine the contents of locked & trapped containers, just in case there may be suspicious evidence. Read all notes, Identify any unusual objects, and then put them back. If the bulding contained nothing but followers of Evil, of course, the whole place is yours to loot.
• All Thieves and similarly suspicious characters not employed by a prestigious organization of Good or Neutral alignment must die.
• Stealing, even from Evil Thieves, is a no-no. Stealing back items that were stolen from you, though, is quite all right (as long as you're robbing the same person who robbed you).
• Grave-robbing: See Points 1 through 4.
• Nalia's Keep: If you are are eligible for the Keep, all the stuff will become yours anyway, so no harm done. The game forces you to play out-of-character, though, as if you don't take the loot pre-emptively, you'll lose it forever. Oh, well. If you are not allowed to win the Keep, it would go to the Roenalls--and Nalia would ask that the party take everything of value with them, to keep the Roenalls from getting their grubby hands on it. Of course this works out best if Nalia remains in the party--if this is not to be the case, be sure to repay her by buying her lots of good equipment, and setting her up where she can form her own adventuring party if she so desires.
• Firkraag: He's an Evil Dragon who kidnaps people and destroys their reputations for fun. The Harpers deemed him enough of a threat to battle him in the past. He shows not even a hit of redemption, or remorse for his actions. If killing him ain't pest control, I don't know what is.
• Killing Rayic Gethras is neither Lawful nor Good. Of course, perhaps your Paladin had his ethics so strained by robbing a church (even a church of a CE god) that upon returning to the Docks, he simply adjourned to the Sea's Bounty to sink to the bottom of a guilty tankard while the rest of the party nicely leaves him out of the rest of the quest's activities. If they want to, they can let him handle the business with Marcus and Hentold in whatever manner he chooses, as a way to cheer him up.
• Mencar Pebblecrusher: "Watch it, dwarf, I'll not take your insults for long," is neither offensive nor an untruth. If he's got a brutality complex, so be it.
• Llyinis: Thievery is not okay. Murdering a child in the course of a burglary is *SO* not okay. Axe to the back of the neck.
• Korgan's quest: From what he says about the Book of Kaza, it's obviously a source of potential magical power, and necromantic power at that. Something like this could safely be left buried, but it seems the cat is already out of the bag--if the Book is going to fall into anybody's hands, it should be somebody who would use the power responsibly and well. If taking this quest will help you make sure that this Pimlico will not allow the Book to be used for Evil ends, then that's all well and good.
• The Golden Skull: Yep, talking to him gives some pretty clear indications that he ain't exactly Mary Poppins. Since the Shade & Elemental Liches clearly aren't the best guardians, a Paladin can either protect the bones in a more efficient manner (leave 1 set in the Planar Prison, and drop the other overboard Saemon's ship, for example), or simply dispose of this fellow altogether--although they would not wear the Ring of Gaxx, unless perhaps in dire need.
