I am writing some fanfic in the form of an After Action report based on my Aegon VI CK2 AGOT mod playthrough. In my version of events, I (Aegon) learned (after defeating the Lannister and Baratheon armies) that I am a Blackfyre. Daenerys is fighting a losing battle against the slaver cities (and Volantis, and Mantarys, and Yi Ti, and essentially everybody in Essos except for Braavos, who allied with her).
I want to procure one of Daenerys's dragons for House Blackfyre, so I try to marry her. In order to do this, I have to help her in her war.
Right now I am writing about Aegon and Dany's first meeting and she is going to show him the dragon pit. I need access to a general layout of her palace (the Pyramid) in Meereen including, but not limited to, her throne room, her dragon pit, and all of the tunnels, halls, and different ways to access the dragon pit.
Is there such a resource anywhere and where can I find it? I could just "wing" a description of her pyramid, but I want my story to fit in with canon as much as such an alternate-scenario story can, including location descriptions. A visual would be nice, and an ideal answer would link to its resources.
EDIT;
Realized I should include where I have already looked. I looked on the Wiki article on the Great Pyramid (because it was the only thing Google produced of worth) and found rough descriptions of the temple complex. I suppose I can use this if there are no visuals to be found.
