Octavian & Ludo:
You follow Abaddon, cautiously of course. OOC, I did have a plan for each path, but I won’t tell you what they were. You chose this path 
[color=green]Abaddon: [color=red]I assure you Ludo, it is not I you shold be angry with. Octavian, you hold the title of Quaesitor? When the Wolf and Owl breed, they produce a Raven. Ravens can interrogate the dead you know.
So my official statement to you as a Quasitor is this. Ludovicio sought me out in search of ancient knowledge, the magical roots of both of our Houses. Not the Theurgy of the Titanoi, that is a later corruption. I speak of the Necromancy of Guorna the Fetid. I speak openly, for my knowledge is so vast that the lesser secrets are like crumbs fallen off of a plate.
But of course, knowledge of how to find me was a mystery of its own. Even when Val-Negra was still attached to the mundane realm we were withdrawn and secluded. Erat Caecus, he is the one to blame. Cut off from the mundane world, the only other way he knew of to get here was through Taglyn. Don’t believe his lies, Taglyn is a very real place. He doesn’t understand though. It has many-many layers.
By now I am sure you know of Metron. He was my prisoner at the time. Erat’s reckless abuse of his fellow Tytalus had inadvertently caused his release. When the Obsidian Ring was broken, everything was thrown into chaos. Ludo would have been lost if he had not been rescued by Berengur of Criamon. The circle sundered, our final anchor to the mundane world was lost and we were cast adrift into the sea of the Magical Realm.
And to answer your earlier question Ludovicio, yes, he opened the Iron Door. But right now that is the lesser of my concerns. I stuck Vanacastium in there, he is naught but a ghost now. I am using his powerful spirit to bind a spell that keeps us tethered to our location in the Magic Realm, lest we slip into the Twilight Void. The link to Taglyn was broken, as I had mentioned. We retain our link with Perdut, but we dragged it into the Magic Realm right behind us, like a ship towing a smaller boat by a cable. Perdut once had three tethers, but they are all severed now. The portal to Jafariya was destroyed some years back, and having interroated Metron myself I understand why that had to be done. The original portal, the one to Durenmar, that was destroyed not long ago and I still have not figured out why that happened. The last one, Barcelona, I had set up magical fortifications to strengthen it but they were insufficient. I could not comprehend the Hermetic Architecture properly.
The last link is Vanacastium, and I can send you back to the material realm through him. You will be deposited on the mundane Mount Periditiu. But I warn you, he is addled by Twilight influenced delusions. He speaks in riddles of some strange prophecy, and the story keeps changing. It is full of holes and inconsistencies. He annoys me. But he is loyal to the bitter end and beyond. I do not need the Iron Door to keep him bound, he holds the spells in place voluntarily. The things that were originally in there, they are harmless phantasms. The collected Twilight ghosts of many magi past. These things, they are not even true ghosts, they are the shadows of ghosts. The Criamon, they understand these things much better. The point is, a bunch of minor shadelings were set free, and Metron has captured and harnessed some of them. I admire the bold accomplishment, for he managed to elude my spies while he hid in Perdut. His power has grown. He has achieved Transformation, and has become a magical being.
Then you come to a huge oaken door. Abaddon stops suddenly and turns to speak to you (first he chastises you for standing on the wrong side of each other).
[color=red]Octavian, you and I can go no further. If you will follow me, I will take you to where you can get a good meal and a room to rest for the night. Ludovicio has an appointment with his teacher. Which brings me to a point. If Ludovicio has suffered from memory erasure, how did he know how to fulfill his quest and return for his reward?
Ludo, do you go in the door or not? It seems like what you are supposed to do, but you have no idea what Abaddon was talking about at all. What quest? What reward? It all seems to convenient, and what little you do remember doesn’t seem to fit with what he said just now.
Octavian, you also have your doubts about Abaddon’s story. He is obviously unfazed by your Piercing Gaze. But anyway, he wants to take you to get food and that sounds like a good idea. You can interrogate him and try to poke holes in his story, try to discover the truth.
