Various metals and special crystals starting appearing around Alexander as he used his "creator" skill. Gods are mortals that after many years and followers they were able to create their own domain using the faith power of the people. Faith power is one of the purest forms of mana made from the worship of people. After collecting many special items and metals a mortal could try making their domain becoming a god or die. 

 But Alexander didn't have this kind of problem, all the special items of the world could be created with his skill and he had a better mana to power the domain with his "Energy body". He didn't want to create a church because he needed faith from people like the other gods, instead, he wanted a church because after ascending to godhood a barrier would form and he couldn't go close to the mortal realm.   

"Hmm, I want the best foundation for my domain, I will use surely mithril and orichalcum, even a little obsidian will do good. I can even add God-Stone that only a domain can create, hahaha I want to see the faces of the gods after they come to my domain".

God-Stone is a special kind of stone that appears at a domain of a god after 1 billion years! If the other gods heard that he could use this kind of stone to build his domain they would go mad.  

After spawning 10 tonnes of mithril orichalcum and 5 tonnes obsidian and 3 tonnes of God-Stone Alexander turned on his "Energy body" and he waited to make the mana around him denser.

"Maybe I could use special herbs and True-Fire to like the devils do."

Devils do not make domains from faith power instead they use the emotion of the people and with special herbs that they gather and the True-Fire from the 9 layer of hell they make their domains. The difference between the two domains is that the God-domain is stronger and has tighter defences but it's too slow to move, instead, the devil domain can make spatial jumps with much lesser energy and it's faster. 

After spawning hundred tolmat (Tolmat is a special herd that it can be found at the 7 layer of hell, It makes everything lighter and with a slight mana reduce for spatial jumps) and fifty Soler (Soler is a special herb that Its like powder and its used for making the domain invisible for a small duration of time).

After teleporting Isabela and Samael that were sleeping after taking too much information, He started placing his materials. Using the purest form of mana he started making a domain that had the form of a castle with a big courtyard in front. Putting as the base obsidian he started his construction, after the Obsidian he used the True-Fire making the tolmat and the soler in a Liquid form and he used at the top mithril with orichalcum. The materials started absorbing the pure mana as they were placed one after another. For the four towers, he used God-Stone. The castle that was humongous started flying and under it, special patterns made of mana started appearing. Many eyes started appearing at the sky, looking for the new god that was about to make his domain. More formations started appearing and slowly ground started forming under the castle. But the ground wasn't made from dirt and stone, but many precious metals like diamonds and gold. When the castle was finished with the towers clouds started appearing.

"This is the hard part." Alexander thought.

Lightning started striking the castle and the ground started shaking. All the eyes looked closer and started wondering If the young one will be able to become a god. After the sixth lighting, the clouds started colliding with each other making a single big cloud. After one minute the biggest lighting struck and the sound it made was like a roar from a Dragon-God. The ground started shaking harder and more mana started being pulled inside the items. After 5 minutes the cloud started vanishing. As the Gods where about to crongatulate the new god the sky turned red. A big volcano appeared! Becauce He used and the two methods now Alexanders domain had to withstand two judges.

Lava appeared everywhere melting the ground as big fire balls started hitting the domain. The mana around Alexander started deplaying faster and faster and more formation started coliding with the previous formations making new and stronger ones. After the sixth fire ball the volcano stopped for a minute before a big BOOM was hearded and a giant fire-ball striked the domain. After that all kinds of colors were absorbed by the materials.

When a god and a devil made a domain, the domain would take the properties of the type of mana they could use.

But as Alexander could use all the types of mana various colors started appearing, from Solar, to moon and even space and Time energy!.

After the huricane of colors stopped no one dared to talk. Alexander appeared infront of his castle gate and A banner started appearing at the top of the gate and at the four towers. It had a man sitting at his throne and two figures at the right and left of him. At the left was the figure of a womain with red hair wearing little clothes that didnt left little for the imagination with black eyes and black wings. At the right was a womain with blonde hair like the sun and blue eyes like the sea, she was wearing a one-piece dress that was white. The banner was half dark-red and half white.

After entering his domain Alexander heard a voice that was gender-less. 

"Hello master, welcome at your domain please select a name for it"

"The faithless castle, that its name"
