I have been debating what lead to follow. Talocan research, relic dark web, or the riddle leading to the Ink of Truth? I know myself, and will be chaotically following all three unless I decide to focus.
I will leave the Talocan artifacts to the Lamp's science team and a friend and scholar from Hedion who agreed to help. And for the relic dark web, that does not require much action, simply lurking around and seeing what is being asked or offered.
So, the riddle it is. The most likely starting point seems to be the "Dark King's bishop". The dark Amarr is a nickname for the Khanid, so I think this refers to King Khanid. Of course, there are many bishops in the Kingdom, none in particular associated with the royal court. Rather than bishops, it has been nobles from the court have been appointed to the theology council in the past. Some may remember that the accursed Sa-Baron Chakaid once got that post, but that resulted from a machination by that evil man.
Historically, it has been the Dukes of Youledian that took on the role of theological councilor to King Khanid. This is true today as it was yesterday: the current appointee of the Kingdom to the Theology Council, Duke Fayed, is again from house Youledian.
The ducal palace, the seat of power of house Youledian, is on Arzanni VII. It has gardens and a ducal museum that can be visited. Time for a trip... with the interbus, given the nuisance of piracy lately.
