Well, as you all very may well know, I occasionally have fantasies which can be mentioned in public. I've been dreaming of a fantasy world in which a fantasy videogame of mine would take place.
I've been speculating writing the adventure of the characters in my fantasy world, but the problem is that since this was that my original game idea would be that it would be a "branching storyline" type game with the outcome depending on the player's actions, and I don't know how to write something like that without making it grossly incoherent, confusing, or just plain ugly to the eyes. So I thought I'd just tell you guys the basic backstory of my fantasy world, starting with the magic system that the game would have depended on.
Firstly, I should tell you that my magic system is influenced by Fire Emblem 4: Seisen No Keifu (Genealogy of the Holy War), if you're familiar with that game at all then you might know where I'm coming from.
Now, the magic system would follow the cliche 'elements' system, with their being several domains, as listed:
Fire
Water
Electricity
Earth
Wind
Healing/Life
Sun
Moon
Time
There is no inherent 'goodness' or 'evilness' tied to any of the magics, as they can all be wielded and used in any fashion the caster pleases.
Now, the way magic works is that you simply CAN'T learn magic. No amount of study or dedication will ever grant anybody the ability to use magic, period. Instead, magic follows a 'sacred/godly/chosen mark' system, where ONLY the person with the mark of a specific domain can use that field of magic. The Mark in question would appear on that person's body and it would be all shiny and ancient and fancy looking, and it would be their to show that they can use magic, and it will stay on that person until they die. However, you can't simply go out and get a mark, the appropriate god has to GIVE it to you, or force it on you, depending on your perspective. However, the only people eligible to actually receive a mark are people that are already related to someone that has the mark. So if someone has the Magic Mark, then their son/daughter/brother/sister/etc will also be able to use magic. HOWEVER, there can only be ONE mark of any given magical domain at any given time. This means, in all, there can only be NINE people that can use magic in the entire world at any given time. Once that person dies, then the mark passes to their closest relative and then they can use magic as well. There is no real ceremony or fanciness tied to receiving the mark, the person dies, then the other person gets it magically.
Now, the ability to use magic isn't the only thing you get with the mark, as (which I'll explain later) the gods consider it a CURSE, and thus upon receiving the mark, you also are given a few other things. Firstly, you receive the memories of every single person that has ever had that particular mark ever, in their complete entirety, from the first person to ever use it to the person just before you. Now, this is 'magical memory' that isn't actually stored in the person's brain, but inside the mark, and can easily be accessed without harm to the person; this is so the recipient's mind isn't snapped in half completely from the huge amount of information that is jammed into their skull. In fact, the person can choose to not even look at any of the memories they're given, but there is one thing they're FORCED to acknowledge when being given the mark, and that's the instructions on how to use magic, what their 'magic item' is (explained later), the implications of their curse, and the REPERCUSSIONS of using magic.
Secondly, the person with the mark gains two more senses: One which simply tells them how much 'life force' they have left. The importance of this will be detailed later. The other let's them feel the location of their 'magic item'. The importance of that will also be explained later.
Thirdly, the repercussions of using magic are simple: normally, when a person in my fantasy-verse dies, if they were a 'good person' by the god's standards (which are kind of warped, in an old greek/roman god way), then they receive the choice to be reincarnated on Earth as whatever they like, or live forever in the afterlife. If they were a neutral person, then they're forcefully reincarnated and given another chance to prove themselves. If they were an especially 'bad' person, then their souls are eaten and digested by the gods for a thousand years, and then forcefully reincarnated to prove themselves again. Very VERY good people are given the above reincarnation/afterlife decision, but with the added benefit that their personal afterlife will be however they want it, a complete heaven made just for them. You don't need to appeal to all the gods, just whichever ones you actually worship, so there's some leeway in that sense.
(For those wondering, the gods are always making new souls, so the world will never be short on needing new souls in order to grow in population.)
Now, magic users, regardless of how good or bad they've been in life, don't get ANY of these choices. Instead, their souls are permanently and irrevocably intertwined with their magic mark, along with the souls of everyone else that has ever had it, to be carried along to the next user and then to the next until the end of all humanity; This is how the 'magic memory' system works. A person with the mark can avoid this fate by simply refusing to use any spell whatsoever, as it's only with their first spell that they're forcibly joined with the mark.
Now, the next repercussion of using magic is that it's not free, it comes at a great cost. Essentially, all magic uses your personal life force in order to work. Life force cannot be replenished, regenerated, or restored in any way; but the thing is, a normal person has so much life force that if they simply stick to casting weak to moderate spells their entire life, they could live out their natural life span without using up all their life force. However, if the magic user is ambitious, and insists on using the more powerful spells, they may end up using all of their life force, and if they do, they die. They don't receive any special or flashy death, they just keel over. It should be noted, however, that merely living uses up a little bit of life force, so even if you don't use up all of it, you're still shortening your life span drastically if you get to dangerously low amounts. Having the extra sense described above helps with this though.
Next, all the magical domains have a special unbreakable artifact tied with their magic power. All the artifacts are special in that they are made of materal which is indestructable, are sentient, and grant the magic user of their domain with extra abilities. All magic users can use the extra sense they're given in order to find their artifact. The artifacts themselves are sentient and will avoid being held, wielded, worn, or otherwise used by anyone except their magic user; They do this by simply vibrating violently until they fall out of the persons hands, getting unbearable hot/cold, becoming purposefully unusable for whatever the unsuitable person is trying to use them for, or, in extreme cases, calling for their specifically aligned god to enact holy retribution upon the offending person. Since they are sentient however, they can be talked to, and while they cannot talk back, it is possible to convince an artifact to let you use it. They are very obstinate though, so this is a bad idea most of the time. Since the artifacts themselves are magical, when the magic mark users are using them, they'll change themselves in order to become easier for that person to use. For example, one of the artifacts is a magic cloak. The cloak, in the hands of it's aligned user, would magically change size and shape in order to be more comfortable for it's wearer.
The magic items also grant their specifically domained magic users with special abilities/attributes. While they vary from artifact to artifact, they all share one thing in common: they all give their magic users the ability to cast the highest echelons of magic available to them. You see, normally, magic users can cast some pretty powerful magic, but the most powerful magic, the type of power that can crush armies, only becomes possible to use when the magic user has their artifact in their possession. Fair warning though, the strongest magic is significantly more costly than any of the others in terms of raw amount of life force that needs to be used to pull it off.
Now, before I forget, I should elaborate more on the genealogy bit of the magic mark. As I said, when someone with the mark dies, that mark goes to their nearest relative. Some of the gods are more sentimental than others, and will accept adopted children as being 'related' since they're CONSIDERED family, despite not actually being blood related. Now, what's important, VERY IMPORTANT to remember is that the gods are keeping count of who has the mark. This is important because as a family line has the mark, it becomes more and more deeply rooted into that family line, and the exchange between life force and magic becomes more efficient. What this means is that while a powerful father would be passing the mark to his son, the son will always be more powerful than his dad was if only because he can cast more magic using less life force than his dad. In this way, it's worthwhile to note that each magic user will often have "Xth generation 'mark name' user" attached to their title, to denote exactly how strong a bond they have with their mark. Very importantly, it should be noted that the bond between the mark and it's holder grows exponentially with each generation, so while their won't be that large of a power gap between the first and fifth generation, there'd be a HUGE GIGANTIC leap of power between the nineteenth and Twentieth. Finally, if for any reason EVERY SINGLE member of any given family is killed, and the mark can't pass to a relative (as there's noone to give it to), then the mark is given to a random child in the world, just as it's being born, in order to continue the magic mark curse on the world. The mark's generation though, in this case, is reset to 1st generation. This happens because the gods really insist on the mark plaguing humanity until the end of days.
Finally, the last thing the mark bestows on it's user is a curse. Whomever has the mark, whether or not they have actually cast any spells to entwine themselves with the mark, will have their destinies irreversibly warped and bent in order to make sure that, no matter how hard they try, they will never escape a horrible and tragic life. The users are told this upon receiving the mark, along with why this is so, from their magic memory. Just like the bond with the mark described above, the power of this curse also grows exponentially with each generation until the family line is completely dead, where it starts over.
Man that was a mess of text, and I hope everyone understands it, because I really like it and I've been able to make a pretty epic storyline in my head that uses it.
