(Third POV)
Deciding on my first use of my FACs I'll shall make my domain, my realm, my territory and new home.
Telling Aillia to use one of the Free Absolute Creations to make my kingdom replying with the typical of course my lord, really need to make my name soon a shining ball of light appear floating before me before rushing towards my chest reading my mind and intentions as a burst of warp energy erupted from me and started taking form.
(General POV)
The Chaos God floated over a ever expanding landmass of black, dark purple, and burgundy forming massive structure a cross between hellish inspiration and Gothic towers and building far at the edge of the landmass was a grand massive dark castle with a structure sprouting from the middle resembling a Gothic cross in a silver with with a burning eye at it center watching over all his domain he'll name it the "Abyssal Watcher" one of his defenses for his domain.
The land started sprouting spikes and alters of faceless angels those daemons that enter his land shall feel weaken more and more unable to approach his "Fallen Maria Temples" serving to be a torment for his siblings legions while his shall be empower he even build a grand cathedral within his throne room making it so his very presence further boosters the effects of his temples.
A living and breathing forge, the first Daemon Engine ever to exist directly connected to the realm of the Chaos God acting as a guard beast immune to all damage, from the void that is its maw endless forges to create weapons, infernal machines, and other daemon engine shall be spawned soon and be ready for war utterly loyal, faithful and obedient he name this Forge Goliath, the Stigeon the Living Forge.
Taking some inspiration from his future brother Nurgle he bestowed plant life to his domain daemon plants both amazing and horrible hungry to feed upon foolish invaders, some of the trees and plant were inspired by Dante's Inferno such as his Hanger Trees, other from other media he read from blood drinking vines, man-eater flowers and more, he made the largest concentration of these daemonic plants near his castle naming it the Infernal Black Forest.
A great lake sprouted in the middle of his domain with the waters having a lovely silky violet tone, made to feed his lovely plants, draw in unsuspecting victim with the promise satiated thrist only to meet a gruesome death this water is raw warp energy great to satisfy himself, his future wives, his daemons, and those worthy of drinking from the "Ambrossia" others are meant to swallow whole both body and soul to feed the lake and the 13 rivers born from it upon making this lake I name after one of Underworld river Styxs some of my largest plants decided sprout there forever drinking from it and what remains of husks of victims naming these new plants Corpse Collect Mangroves another fitting death for those that enter my realm without my blessing.
For now that is all I create from the outside of my realm with the FAC, is hellishly beautiful in my eyes all the rest of my focus went to castle and home I name "Castle Oblivion" hey KH made a cool castle and name, also it doesn't exist in this world so I can use it as I please aside from my Abyssal Watcher capable seeing all in my domain I grant with other abilities it immediately alerts me, and those serving me of invasion, getting a certain distance into my domain the eye fire raw warp energy dissintergrating all hit by the beam, aside that the many trails of Carnage and being inspired by my future sister this time Lust and Punishment await those that manage to enter the first of thirteen level of my castle.
One of my thirteen level shall be dedicated to my future Greater Daemons and Princes, this level shall be known as Infernum Sanctum, another level is exclusive to my wives to reign beside me and even command my legions when I'm indisposed I named this level the Blood Queens' Sanctum.
The 13th level is my throne/personal chamber design to my desires said throne room serves as the main Grans Cathedral of the Fallen connected to all my temples both stylish and functional.
With this my realm is complete fully designed to drastically aid my legions while weakening and slaughtering my enemies I then named my domain the Nethervoid for it daemonic beauty and never ending expansion when I was mortal I never understood why the Chaos Gods didn't add more things to their own domain to aid them they were do caught up in their Eternal Game, they never focused on improving well I won't everytime I can I'll shall not only improve my realm but my force both the Materium and the Immaterium shall bow down to me especially once I finish my God-weapons.
As I admired my work Aillia informed me that I have achieved several quest completions I told her I'll check them later, first I told her to use my last Free Absolute Creations to make my weapons that will rival even my future brother Khorne's End of All Things I need these weapons to not only be able to kill other gods but give my future siblings something to think about before challenging me.
