Ok this is my first post. I often get on here and watch everyone else post...But I was laying in bed after playing entirely too much ffxi and began to think about the elements and how they correlate (if this has already been dreamed up, forgive me. I am nub sometimes.). Also this has no game pertinent info, it is strictly composed of my late night ramblings. I hope you find it at least sort of interesting ( :
Anyways, here goes.
So we have eight elements, fire, earth, wind, water, ice, lightning, light, and dark. Im going to divide these up into 3 categories, elemental, composite (made of more than one), and aligned (forced of "good" and "evil").
Lightning (is a plasma, superheated air. Fire+Wind)
Ice (solid and composed of water. Earth+Water)
These can also be divided as Light or Dark elements, which I perfer to call Kinetic (in motion) and Potential (contains the possibilty to be put in motion but is naturally still).
Light (one could say Light is the dominant Kinetic element. Perhaps being comprised by Fire Wind and Lightning)
Dark (same as light...only...backwards lol)
Pretty much obvious. But what I think is interesting is how drastically they impact vanadiel. Even the nations seem to be aligned with particular elements based upon the races that live there. This is purely speculative so feel free to add in. But I think...
Earth (Galka(High vit))
Lightning (Humans(balanced stats but very innovative))
Water (Religous (High mnd))
Fire (Warlike (High str))
Ice (Taru (High int))
Wind (Mithra (High agi))
Elements also determine stats of course. One can plainly see this from the rings we can equip.
I put this in the BLM forum though because I thought that I might figure out why we get certain spells in the order we do. This assumes the Black Magic uses existing elements in the area around them as material components for spellcasting. Also explains why magic is amplified during certaing weather (there is an abundance of a particular magical energy in the environment)
First we get stone. It throws some rocks up from the ground. You always have ground (unless your in the air...). Because it is such a basic, stable, and readily available element it makes perfect sense that this would be a young BLM's first spell.
Next is water. Water, like earth, is everywhere. Perhaps the BLM concentrates the water particles in the air to converge on a targe. Just a thought.
Now we have aero, the wind spell. Air is far more common than earth, but because it is an element in constant motion (a kinetic element, see above) it is far more difficult to control.
Then there is fire. I can only imagine that the use of fire either requires the concentration of oxygen which is then combusted with a magic spark (like Mustang from FMA) or the air is just super heated. I really have no idea here >.>
Then we have Blizzard. Perhaps that the BLM combines the elemental energies of earth and water (both potential elements thus easier to control. also explains why you get Blizzard before Thunder) to create a solidified water, or a giant spikey ice ball.
Lastly there is Thunder (strange since Thunder is the sound Lightning makes. Oh well). If combining two potential elements is difficult I should imagine combinging two constantly moving elements would be even more difficult. By superheating air, you get plasma, which is effectivley what you see when you casy the spell. It is more damaging than the other spells, possibly because of the fact that it is constantly in motion and is damaging on its own. Ice only hurts when it hits you, but electricity can hurt simply by coming into contact.
I cant really put too much speculation on Light and Dark. Light is most likely Divine and Id rather not think of where dark spells come from.
I would imagine the elements hold sway on jobs too. At least the basic jobs.
Warrior. I would say fire, but Im really thinking its lightning.
Monk. Earth, hands down (no pun intended).
Thief. Wind. Just look at dagger WSs
White Mage. Water. Heavily affected by the mind stat.
Black Mage. Ice. Int stat.
Red Mage. Fire is the only one left. Fitting of the crimson armor.
This is all I can come up with at the moment. If you thought it was interesting let me know ( : If not I understand lol. Feel free to post your own insight onto the world of Vana'Diel's elements!
