[X] Plan What We Can Say
-[X] Tell him that the House of Black and White splintered. The larger part willingly bent the knee, while some others broke away and left the Imperium to parts unknown.
-[X] Where they went and what they are doing now is being investigated by the Inquisition, due to concerns what a rogue death-cult might turn into.
-[X] You are assuming that the Dragon didn't accept their oaths without more detailed knowledge of their inner workings, but this information is above your pay-grade.
-[X] However, you consider it likely that the relevant knowledge would be on the table, if Marwyn were to ask the Dragon personally for it. Especially if he is willing to share the knowledge of the Citadel in return. Especially the tomes that some are trying to bury in it's vaults.
-[X] Suggest a formal meeting between Marwyn and Viserys Targaryen in the coming days on neutral ground and off the books. Ask Marwyn what he is willing to offer in regards to cooperation and what he would ask in return.
