SPECIES:
Velucri- Tall, thin, and generally adept with technology. They're covered in feathers, but lack wings, beak, or birdlike feet (hey that was a slant rhyme). Lifespan's 75-85 years.

Hjorta- Quiet, reclusive mountain dwellers with hooved feet, and small, curving horns.

Taska-A species of well-known farmers, with serpent body figure, feathers, and a beak. They take pride in their use of modified farming equipment, redesigned for war.

Krowak- Simple tree-dwellers with limited flight, small size, and simple culture.

Avaz- Vicious saurian folk who live to defeat others.

Draconians- Now wild animals

San-Krat- DO NOT EXIST ANYMORE, rip

Snetryuk, mysterious dwellers among the ice, nomadic and fond of masks.

Mechani- Metal constructs from the old world, ingrained in routine and stubborn that their masters still live on.

METALS:
Midnight iron, an alloy that makes a stronger variant.
Twilight steel, same rule applies.
Hellshard, a ~secret~
Tungsten, hard and tough.
Cobalt, same rule applies.
Chromium, good for decor.
Quicksilver, hard as steel, valuable too. (Yes I know it's actually mercury.)
Palidiun, a very expensive alloy.
Umbratium, one of the best metals you can find.
Veridentite, lightweight, but pretty worthless otherwise.
Malstrom, iron-strength metal.
Aluminum bronze- Bronze, but ~ALUMINUM~
Solid Hatred, Sharp, heavy, and for weapons only.
Solid Willpower, Light, flexible, but hard and tough.

The weapons are scattered about the civs, it's a surprise!
Screw that I'll tell you them.
Kris swords/daggers, wavy lookin' blades that have a chance to hit again, after a miss.
Katanas/thelike, great for slashing, poor for stabbing, anime fortress gogogo
Broadswords, wider slicing, less useful for stabbing
Xiphos/the like, heavier, useful for both stabbing and slicing, no flat to slap with though.
Sickles/Hatchets/War axes/naginata, more axes to play with
Harpoons, MAN YER LIFEBOATS
Staves, only one civ uses them in place of spears
Etocs! Great for shanking, less great for smacking.
Gavilan- This. http://images.ontheedgebrands.com/get/w/245/h/245/A17-AT5710.image?notfound=notavailable

New horrors!
Slade/adamantine collosi. Exactly what it says on the tin.
Wyverns. Moar dragons
"Jagged statues" Basically like a rock-man except worse
"Hollows." Infectious zombies
The old gods, a horrid pantheon of creatures/constructs/whatnot that for now pop up and wreak havoc. I'll be adding a system that allows you to summon them, decapitation may vary.

Some new dishes/instruments/plants too, nothing major.
Copperroot/Ironwood trees, have fun chopping down swords.
