Choose how the story begins

Day 1 of the beginning of the collapse of civilization. Currently everything is normal, the city carries on like every other day, the various races either mingle or tolerate one another due to their jobs and or school.

It's reasonably early in the morning, you start to stir awake as you hear a very grating and annoying alarm ring. People are preparing to go to their jobs, School will be starting soon and thoughts of whether to try and attend to your duties, just get through the day without being noticed or perhaps even to bail on your duties altogether and just do whatever you desire today, all run through your mind.

Ok! This was a brand new endeavor! This is using a brand new add on frame compared to any other Castory frame prior, based on a design method I used for an old DND style campaign, I call "npc frame". Because the land structure design really is an afterthought in this and civilization has fallen, there is much point to crafting it out the way I did my medieval or modern grand Castory design, so instead I designed the world, it's situation, the condition the land was in and the relationship between the races. After that I made short entries for important npcs that all lead factions relevant to their race, they all have brief physical appearance and personality quirks and each faction has their own situation and relationship to the other factions! Every faction has 2 leaders who may have aligning or opposing views. If you aren't dealing with a faction, then it's pure walking dead style chaos out there heh.

Now! Important note as this Castory has some lore framework to understand before playing. It is heavily inspired by Parasite eve, Resident evil 7-8 and walking dead.

Firstly "Mutant Prime" is exactly what mitochondria Eve is in Parasite eve. An individual who's mitochondria has awakened and become sentient and completely taken over it's host. They are a force of cold nature and almost all races will flee on site from them. To understand, they can completely control the mitochondria cells within themselves and any within a 1 mile radius of them to manipulate their bodies in a ton of different ways, ranging from essentially making organisms combust and die, liquefy or turn into monsters. Generally as a power, mitochondria can influence a body to do almost anything biologically you can think of on the grounds of relevant biological mutation, growth, restructuring, heat conducting, electricity conducting and even influencing geomagnetic forces. Mutant primes typically are cold and detached from the other races, viewing them as interior organisms, some seek to work towards creating the ultimate orgaism (is what mitochondria eve aimed for) or they can revel in their newfound power and seek to claim a dominion of their own and amass power and resources as some kind of ruler. If you want to play as one, note yourself as "Mutant Prime" in your persona. Note, many have subtle or dramatic mutational changes to their body that easily sets them visually apart from the race they originally were, so keep that in mind when constructing persona design.

"Mutant Familiars" take on the role of those that were turned by Miranda in re 8, think Lady Dimitrescu's situation. They can only be turned and made by a mutant prime or a mutant vessel. These individuals have had their mitochondria forcibly awakened and made sentient and though they retain their personalities and minds, they are under the control of the prime who turned them. Some will obey their prime willingly while others curse every second they spend in their situation. They have similar abilities to a prime, but cannot influence a prime or a vessel. Many have subtle mutational aesthetics or none at all and have unique powers but sometimes may hide grotesque and or monstrous forms. If you want to play as one, note yourself as "Mutant Familiar" in your persona, and you don't have to worry too much about visuals as the mutational aesthetics are not strong unless you want them to be. Enjoy your life under a prime, or maybe you'll get lucky and be free if your prime dies. ;)

A "Mutant Vessel" is exactly what Aya Brea or Alice from re movies is. They are individuals who have a resonance effect with what is trying to take them over and are able to hold back their mutation in exchange for controlling a degree of the power and being immune to the influence of a prime or familiar. A vessel has almost all the same powers as a prime without affecting those around them and are able to create familiars of they wish. Vessels have complete visual freedom as they retain their mind and personalities completely and can hold their mitochondria at bay to resist being taken over. They have the option and potential to give and become a prime or ascend and become a being with complete control over their mitochondria instead of it taking over them. Some are not even aware of what they are until a prime or familiar tries to infect them only to find they will not combust, liquefy or change like others around them. If you want to play as one, put "Mutant Vessel" in your persona.

This was a little ambitious of me, all fantasy races are available here and the tone is post apocalyptic with a walking dead tone, with resident evil mixed in due to the parasite eve monsters.

PS:... If you play as any race that is not an angel, demon or spirit and you come across a prime or familiar, I would recommend you run. (Unless you are a unique build with some kind of genetic/biology based resistance.)

Finally, magic is not stated in this world and isn't really a point, so treat this as a science fiction horror with some supernatural throne in.
