Already plans were beginning to form into your demonic mind. Your mind systematically created new ideas and then immediately scraped them, keeping only the good ones as you began to go into a long deep as you layed down on your bed.
You felt that as a demon you shouldn't restrict yourself to the power of only one sin, but should instead explore the other demonic specializations as well.
Then after several hours of constant thinking, your perfect idea had come. Your plans were simple but intuitive. Using the power of the sins of Lust, Envy, Sloth, and Wrath you would create your new empire.
Using your new found powers of demonic shapeshifting you would be able to create your own specialized demons, each with their own abilities and perks. These demons would be classified into one of the four sins you had chosen.
There would be:
Wrath Demons: Or Devils as you called them. These demons would be your foot soldiers, with strong powerful muscles and with proper training in both physical and magical aspects these demons would be your military might. Devils would be ranked not by military standards but wolf pack standards instead. By having your devils fight for superiority with each other you can ensure that only the best are able to lead your army, be it with strength and brute force or with cunning and intellect.
Envy Demons: Fiends as they would so be called would be the religious and intelligence class of demons. Unlike Wrath demons they would be fragile but would more than make up with it with their superhuman intelligent. Fiends would both be the research scientists, engineers, and religious figures of your empire. Using Envy magic they would find followers for you, allowing you to gain power from them worshipping you. Fiends would also study and dabble into magic finding new arcane knowledge that could be around the corner.
Lust Demons: These Succubi would be the main corrupters and breeders of your empire. Not only would they breed and produce more demons of different types they would also be able to transform their victims into loyal demon for your empire, also giving you power as your succubi would purge their humanity and feeding their once human soul to you, to be replaced with a demonic one instead. Succubi would also become your food farmers, livestock breeders, and interrogators(for obvious reasons).
Sloth Demons: The last of the four sins you've chosen, Sloth demons would be your scouts and intelligence network. Using specialized stealth magic they would search for potential targets for you to corrupt and add to your demonic roster. Sloth demons would also be your assassins and spy's as well. If any mortal needed to be shut up quickly or quietly, your sloth demons would be the ones fit for the job.
That was your plan. Now all you had to do was to set it in motion and watch as your new kingdom grows everyday.
