TSR Code:

'"Ye want this ol' moneylender's advice on entering Halaster's Hall yet again?  My advice is this: Don't.  There's precious few treasures worth the death and agony and fear you'll face.  Your problems are twofold: First: ye've walked its halls before, and Halaster pays attention to those who visit him frequently (and he's the one you don't want to have watching you!).   Second, you're looking for the lair of that lunatic wizard-murderer from Trades Ward.  He's a dangerous lot, that Maddgoth, and many others met their ends by underestimating that pasty-faced little scarecrow.  If you're looking to lay siege to Maddgoth's Castle, you're on your own - I've not visited it, and i'm not likely to, either.  Truth be told, no adventurer i've heard of looked for Maddgoth's lair and returned to tell of it.  Not that this scares bold heroes such as ye be, right?   Well, the path to fame allows fools and champions alike, though fools often listen better than heroes.  Until out coins are shared again, good fortune".  - Mirt the Moneylender'.
