Contemplating a 27-point alignment grid. Basically, adding a Z-axis to it. In addition to good - evil, law - chaos, having strong - weak. So you could be Lawful Good, or Strong Lawful Good, or Weak Lawful Good. Weak basically means you won't take any real risk for your alignment, normal means you'll take acceptable or moderate risk, strong means you'll take major risk. So True Neutral tends to be generally balanced ethically, not strongly taking sides in many things. Strong True Neutral will specifically not take sides in things, and will seek a balance in everything. Weak True Neutral is basically unaligned, with no strong views toward anything morally or ethically and probably just doing their thing and wanting to be left alone.
Neutral Good helps the weak or helpless, weak good generally is kind and probably gives some spare coin to beggars, strong good dedicates themselves to helping the oppressed and gives greatly of themselves for others. Weak lawful evil will gladly benefit from a slave-owning culture, lawful evil will gladly own slaves personally, strong lawful evil would be willing to enslave others actively for their benefit.
That kind of thing.
Continuing race revision:
The dragonborn are a nearly amazonian society. Females run all aspects of the culture: owning and operating businesses, managing government, military and guard service, etc. Females have a strong connection to community and organization, and a strong lawful streak in alignment. Males, by contrast, have a strong leaning to chaotic alignment. Males tend to be wanderers, vagabonds, and are generally considered unreliable by the females.
This is not a form of discrimination, but a species-wide fact. While there may be exceptions, the vast majority of dragonborn fall into these definitions. This may be due to the way the species lives and procreates. Females lay eggs, and generally select a passing male who they find promising (or at least unoffensive) to fertilize the eggs. The male then moves on, with no connection to the young he sired or the community he is in.
Egg-cycles are not fixed across the race. Some females are especially fertile, and may lay a half-dozen eggs every year or two. Others are, more commonly, slower and may lay 2-3 eggs every 3-5 years. A small few dragonborn females are barren, or egg-less. Contrary to what humans may expect, there is no social stigma to being egg-less, and in fact is generally seen as a sign the female is intended for greater things. Many egg-less end up as priestesses, military commanders, politicians, and sages.
Females tend to develop strong yet wide connections to other females as close friends. Males tend to be solitary or form into loose groups of a few other males, often no more than two or three. Romance is an alien concept to dragonborn, who do not feel sexual attraction unlike most humanoids. It is not that they reject or vilify such concepts, simply that they cannot truly grasp them.
Dragonborn society is religious, but also in a way unusual to humans. The great dragon-god, Io, is revered most highly as the progenitor of the race. Io, being genderless, is seen as impartial and having both feminine (lawful) and masculine (chaotic) aspects. Io is a figure more of divination and insight than a moral compass. Cults to Bahamut and Tiamat also are not uncommon, though their priests tend toward neutrality as they see both as merely aspects of Io.
Ever practical, dwarven society is egalitarian across gender and wealth lines. While varied by region and nation, the core of dwarf society is typically run by a combination of a monarch and a council. The council is generally made of high priests, sages, and clan leaders. Monarch is an appointed position, chosen by the council from the best young (no more than 50 years usually) candidates. The appointed king or queen then reigns, with the guidance of the council, for as long as they are able and willing. It is expected that the monarch will marry, and the married-monarch generally serves in positions of public relations and morale.
Dwarf society is highly religious, revering the Soul-Father Moradin. As a whole, dwarves believe in reincarnation. This is a dwarf-focused belief and they do not necessarily believe, or care, if non-dwarves reincarnate. The belief is that at death the dwarf soul returns to the forge of Moradin and is remade then sent to be reborn. This reforging can change a dwarf completely, including across social and gender lines (possibly accounting for much of the egalitarianism). Statues of great heroes and monarchs are built, but as a remembrance of great deeds and as an example of behavior, not to commemorate something they feel has long since been reborn.
By extension, dwarves believe in fate. But fate is person-specific and not world-wide. The Soul-Father made them for a certain task or role, and grants them a certain span of life. A dwarf's fate does not interfere with others or the world as a whole. This ties also into egalitarianism. If a female dwarf seems suited for war, who is to argue with that? If a male dwarf seems disposed to take care of children, well then he should tend to children... the Soul-Father doesn't make mistakes
The only real gender-splits in dwarf society are: high priests (always male), and town guards (hearth-guard, always female). High priests of Moradin the Soul-Father must be grand-parents, and the stronger the family they have raised the better. This is seen as a connection to Moradin. While the dwarf military has both genders, only women are in the town guard as it is seen as rightly the privilege of women to be the last line of defense against evil.
Dwarf culture otherwise varies quite a lot based on area. Dwarves tend to live in places most races find difficult or rugged: mountain-sides, deserts, islands/coast, swamps, tundra. Whether dealing with a pitching deck of a ship, shifting sand of a dune, changing tide of a salt-water marsh, or slickness of a glacier... dwarves are stable on their feet and durable.
The only mechanical variation is dwarven weapon training. The default represents mountain dwarves. Sea dwarves (islands and coast) instead have short sword and hand-axe. Desert dwarves have scimitar and falchion. Swamp dwarves have battleaxe and longsword. Arctic dwarves have longspear and war pick.
Elves, both high elves and wood elves, are exclusively male. In time immemorial, they lived in immortal peace in the feywild. When violence shook their peace they came into contact with mortal races. Of those races, most useful to them were humans.
Elves can breed with nearly any humanoid (dragonborn are a notable exception). The result is always a male child and an elf. The exception to this is with humans. With humans a child may be male or female. If male, the child is an elf. If female, it is a half-elf.
Charming, alluring, passionate, artistic, lithe, athletic, mysterious... there are many attractive qualities of elves. This is one reason, despite lacking females of their race, they manage to preserve their numbers so well. This, combined with incredibly long lives (many say they are technically immortal still), has kept the elven races alive since the dawn war.
Elves are passionate, and frequently take lovers of their own race or males of other races. Though no children can come of this, that just makes the elves feel more free. In truth, most elves would find the idea of stifling their desires due to any social stigma attached to homosexual pairing to be confusing or downright insulting. Flighty as they are, elven flings can still sometimes go beyond one night of passion to months, years, or even decades of romance.
Culturally, the chaos of the fey leaves most mortal races confused. Their rulers change frequently, often over challenges brought by other elves, or simply boredom with the position. This is perfectly natural to the elves, who seem often to hold court in Eladrin cities purely for the spectacle and ceremony with no real concern as to laws or governance.
A exclusively female race. Half-elves are the daughters of elves and human women. They are as varied as the humans who birth them, but always with a mercurial touch of the fey to them. Half-elves may only bear children by elves or humans. If the father is human, the child is human; if the father is elf, the child is elf. As such half-elves are always the direct off-spring of a human woman and an elf, they are not truly a growing race of their own.
The halflings are a race that lives by travel. Halfling communities, if they can be called such, as generally a few extended families living on a large river-raft, on a boat (where they often join forces with sea dwarves), in a caravan, as mounted nomads, or some other form of transit. This could be seen as simply racial wanderlust, and often is by non-halflings, but is actually part of the halfling connection to fate.
On an instinctive level, Halflings have a sense for destiny and the tides of fate. They often let the stars guide the travel of their family. Divination is seen as semi-sacred. But destiny is not an unmoving thing. One's fate is never set in stone or restricted to one place and time. It is ever-flowing and shifting, the threads of many fates weaving together over the fabric of the world to tell the tale of all. So it is only natural that the halfling people should move with it, letting fate and chance carry them to greater things.
Halfling society is matrilineal, one traces ancestry through the mother. This is a matter of practicality more than anything: it's easier to keep track of who your mother is, even on the move. Marriage, as humans know it, is uncommon with halflings. Fate rarely puts two people together for a lifetime. Instead, relationships and lovers are fluid over a halfling's life.
Similarly, halfling culture tends to be slightly matriarchal. But this is really just that clan-leaders tend to be the eldest grandmothers. The wise crones of halfling society are well-respected by all, men and woman. Otherwise, there is little difference seen between men and women in the culture.
