New Distant Folk civ:
Huang - a race of sentient, ceramic humans. An enigma to many, the Huang view peace and tranquillity with utmost respect, and simultaneously strongly admire martial prowess. Like the Hito, the Huang use some unique weaponry, such as the dagger-axe and the guandao. Generally, the Huang prefer to settle on savannahs and grasslands, and tend to avoid wetlands and rainforests as the humid climates don't mix so well with some ceramics.
If you've figured out castes now, it'd be pretty cool if you had the vast majority of the population made of earthenware, a small proportion made of stoneware, and then just a few porcelain. The rarer ones would be denser which could help out in combat, but if you wanted to do some fiddling with skills to make them extra-special that'd be pretty cool too.
If you haven't figured out castes, or you just really wanna drive home the terracotta army theme, terracotta is a kind of earthenware.
For reference, the dagger-axe is approximately halberd-sized, and is essentially exactly what it sounds like; a dagger-on-a-stick, swing it at a guy and it's basically like stabbing them but with some bonus momentum and range, and the guandao is basically a glaive, a large blade on the end of a stick, but that one slashes the guy you swing it at instead of stabbing like the dagger-axe.
New People of the Wild civ:
Arak - A race of cave spider men, subservient to the same dark lords as the goblins. Armok help those who settle too close to an Arak pit, the cave spider men can sling webs just like their giant cousins, though their bite is much less potent, causing only localised paralysis. Though their natural weapons make them formidable opponents, they do have some flaws: unlike goblins, they are not immortal, and therefore do not generate the same ludicrously huge population, they also do not keep domestic animals and can only forge metal into maces, large daggers, and bucklers. They may be incapable of forging armour, but an edged weapon made of anything lesser than steel is unlikely to cut them, as they make their clothes from their own silk, which, due to a demonic gift, is a little tougher than iron, though it won't protect them from a good hammerin'.
