As you arrive at the location that Boudacia indicates she thinks is Royst's home, both Tamlara and Alex will confirm it is the right location.
You see a relatively large 2-story house that is very nice looking. This by no means belongs to a poor commoner, and while obviously the home of someone wealthy, it is not overtly extravagant either.
When Boudacia knocks on the door, a servant opens the door and asks you to please state your business. Upon telling him that you are here about the job offer to map the Spire, he will escort you to a sitting room & ask that you wait here "without touching anything please!" while he summons the Lord Abernast. "It may take some time for him to present himself as he does get absorbed in whatever current 'hobby' he is dealing with. Please be patient."
After about a half hour or so, in walks Lord Abernard Royst. In a rather gruff tone and at a fairly quick pace, "My! You are a rather large group of adventurers aren't you? Good! The better chance for success rather than death! I am Abernard Royst. Well, I hope your not wasting my time! I want maps of the spire! As detailed as they can be! And any additional information or notations to go with them! I will pay according to the quality and amount of danger involved per each map that you bring me. Now! None of this trying to scribble 3 or 4 itty bitty maps on one parchment to save paper! I expect you to use at least one full parchment per level! The rewards start at 300 Gold pieces and for a map that is very well done & for which you had to overcome enormous obstacles ... well, who knows how much I might be willing to pay! Just so you know I've been known to pay as much as 20,000 for the BEST of stuff! The gods - and the scoundrels of the Hellknights and perhaps some thief or two as well - know I've got the money to spend! After all my years adventuring and all the different treasures I brought home!
I have another task for you as well, that I didn't want posted publicly on the board. First let me warn you all that while you were waiting I had servants write & draw detailed descriptions of each of you as they observed you through magically concealed peepholes in the walls. A servant is even now on his way to the Citadel with a sealed package containing magical copies of those descriptions. The package has instructions on it, that it is to be opened in the case of my untimely death or in the case of a robbery occuring at my home and there is a note in there saying you are the most likely culprits. Don't take this personally, it is a measure of precaution I have to take as I am about to show you my most prized possesion!"
As he says this he turns towards a cabinet by the wall and you hear him muttering some arcane words as he waves his hands around. Those of you with arcane abilities are fairly certain that he just dismissed or de-activated at least one spell, possibly more. He then pulls out a chain that hangs around his neck, under his tunic and uses a key on there to unlock the doors on this cabinet. Behind these doors you see several compartments and drawers, many with locks of their own. He moves to block the view of exactly which drawer he is accessing as he uses yet another key on the same chain to open that drawer. When he turns back around to the group you can all see in his hand a small piece of metallic looking crystal, that is a pale green in color. It is about the size (NOT shape!) of a finger joint, and is serrated on one edge. Quite clearly it is a broken off chip from some sculpted item.
"In and of itself this has very little monetary value, though it is made of a an extremely rare substance. It is the skymetal Noqual and it is very resistant to magic. But it has great sentimental value to me! The last adventure I ever participated in. My dearest friend, companion, fellow adventurer, and fiancee, Shantleen had found this and was fascinated by it. She really wanted to find the rest of it to see where it had come from. Alas, one evening as she was studying it, she failed to notice the skeleton that came up behind her and stabbed her in the heart. She died instantly. Now, if you should find the sculpture that this came from and let me know everything you can about it! And if you should be able to bring it to me! I shall pay no less than 3,000 gold for that! As I said, it is not valuable in itself, it is just for the memory of my dearly departed Shantleen. Now, unless you have questions for me I must get back to my research! Joaz will see you to the door!" As he starts to walk out of the room not expecting any questions to be asked.
