Thanks for the comments, guys! I did not expect the city to be so liked. Here is the next part:
The Lairs of Power: Genesis Ziggurat, Nana Hill and Enlil.
On the northern side of Plinius Crater stands the Genesis Ziggurat. This is was the first structure on the crater, and it is shaped like a ziggurat -it, and the wall surrounding the Black Forest, are the only structures actually built in the sumerian motif than gives the city its names. Since it was built long before there was a dome, it is a sealed construction, and most of its structure is actually underground.
Before there was a city, the ziggurat served as Genesis C&D headquarters, and hosted the Genesis Research Centre, where it designed, built and tried the company's construction drones (many of the crater's main buildings were built that way, even before there was a dome -or an actual city- planned). After Genesis created its genetic division it also set up its labs there. Eventually, the headquarters moved to Marduk Castle, and the droid design facilities moved to the industrial area in Sumugan Gate; only Genesis Genetics remain in the Ziggurat, which official propaganda claims is mostly abandoned. With the kind of gossip and myths than have sprung form the existence of the Black Forest, and the relish Mardukians show in telling visitors about the “hidden” forbidden experiments going on inside, no one is sure whether to believe the propaganda.
Around the Ziggurat grows the Black Forest. It is surrounded by a brick wall copied from the ruins of Babylon, with a brightly glazed gate and a scenic avenue, flanked by lamassu, than reaches the ziggurat stairs. Even those onlookers than don't know then entire forest only took a few months to grow, occasionally think there is something subtly wrong about the walls and the trees... and then they notice than the watchtowers are facing the wrong way, and is it just me or those tree limbs are closer to us than before?.
That is because the forest is entirely made up of pants than Oscar designed and handwaved. While the actual quirk than makes him 'wave vampire and/or carnivore plants is not widely known... the fact he keeps creating those plants is. The forest is very lush, though it seems its green is a few shades darker than normal. It is filled with small forest creatures like rabbits or squirrels, though no predators (and somehow the population does not increase...) and the tree limbs do show some tropisms. But the gossip and tales... no one will confess to have visited the forest, but the wilder and more lurid the tale, the more it will be repeated. Giant man eater plants, walking fungi, sentient Ucorn trees in the depths of the forest, and absolutely everyone in Marduk will swear than, while the outer wall only looks two or three miles long, you can get lost inside the forest and walk for weeks before finding civilization (not that you will, because the daisies will have eaten you by then)
Closer to humans, and covered with vegetables than, hopefully, are not plotting the Downfall of Humanity, is Nanna Hill. It is in the northern part of Marduk city itself, and is mostly a public park. On top of the hill rests Marduk Castle, a huge structure which probably has far too many towers, crenellations and gargoyles, and the headquarters of Genesis (also the private residence of Oscar Vykos and his AI family). The gargoyles change places and positions from time to time, when Bernie claims to get tired of the design. The rumours about the fact that no one eves sees workers actually moving the gargoyles, or about Genesis having experience in building all kinds of construction droids, which may not be that different in construction as defence droids, are dismissed as conspiracy theories
(sometimes it seems there are many, many conspiracy theories in Marduk. One of then, for instance, claims than Oscar is a firm believer than a Gothic steampunk city ruled by a vampire should be full of conspiracies and secret societies, and so happily spreads as many contradicting rumours as he feels like)
South of Nanna Hill, and sprawling on its slopes and the small valley in the centre of the peninsula, is Enlil District, the government district and the biggest concentration of monumental buildings of the city.
Long time residents will be able to point you the old prototype, pre-dome buildings (in general, bigger, grander, and of wide range of styles) and the newer constructions after the city was founded, with are usually in victorian neogothic or neoromantic styles, trying to meld all the older monuments into a whole.
The whole sector is a showpiece of palaces and avenues, but the Cortes Palace towers over then all.
The Cortes are both the parliament, city hall and cabinet of the city. Oscar Vykos ruled the city as, basically, an absolutist prince while it was being built, and for the the first two years (the Boskonian wars; he had not planned for it to last that long, but after a scare about a Boskonian infiltration attempt in 2013 he decided no take no chances of a chaotic change of power in mid war)
Two weeks after the Fall of Boskone Prime, after the celebrations fizzled out, Oscar announced than he was stepping down, and the the city would have an elected government from then on.
The head of government is the Canciller, elected in a crater-wide election every seven years. He can chose a vicecanciller, but all other ministry positions must be voted by the Procuradores in the Cortes.
The Cortes is a council or representatives. Every five years, the eight city districts, the six villages, and the Plinean University choose one Procurador each. There are two unlimited terms, for the current Commander of the Watch and the Archdruid (this is the fancy title given to the head of the life support and city planning department).
Currently there are also life Procuradores, which are voted by a two-thirds majority of the Cortes for several achievements; they can attend the sessions but usually have no vote. Extreme situations grant then a vote (they have never happened, since they are emergency powers like a declaration of war or sanctions against a foreign power, and they have not happened so far since the creation of the parliament). Once there are four honour Procuradores (there is just two of then now), they will also have veto power with an unanimous vote.
The current two honour procurators are Oscar Vykos and Sharon Cobbler, a motherly australian doctor than moved to fenspace to live with her fen children after a nasty divorce, and who more-or-less single-handedly built the Marduk Health Service.
