Michael,
The Thain of Clan Gruhnstubhle has replied to my response for a meeting to discuss the particulars of the construction project.
It is ordinary in arrangements like this, at least on the surface, to offer a "gift" to the person with whom you are making the arrangements. I dont know for certian if this is a tradition here in the Underdark, or among the Duergar, but I feel it will be prudent that I offer something to him during our conversation, as we near the close of the official "deal".
If I dont meet you before then, I'll be happy to front the coins, provided you can assure me that they will find their way back to me. I hope you wont confuse this as greed.
Sincerely, - Cog
