The idea of using tattoos to contain magic powers is not a new one. The Ink gauntlet follows the basic premise of using rare and precious inks to inscribe spells into the skin of a mage or would be spell-imbued person. Some of these inked spells might be permanent, while others might fade after being used once, or a preset number of times.
In the days of old, before the dominance of humanity, the giants were the supreme rulers of the world and their crafts were considered to be the best. These beings venerated the god of the forge above all others and their swords and armors were the best that could be had even in the days of their decline. A hero seeking a masterwork sword might have to voyage long and hard to find a surviving giant smith or cache of rare and valuable giantcraft weapons.
Pcs learn of high power magics that allow them to banish weapons and suits of armor to some 'elsewhere' place until such time as they need it. reduces encumberances, gets fewer questions, and when the PCs get jumped by thieves in the ally, they can summon their suits of full plate armor with weapons drawn.
Lesser powers would allow them to summon their weapons from another physical place, drawing them to their hands like Luke skywalker summoning his lightsaber on Hoth.
The Macabre style of architecture is common in ancestor venerating societies, or societies that have been afflicted by a long term period of loss of life. The style is best noted for its use of a morbid and gruesome, skulls and bones, severed limbs and the like. It also alternately honors the spirits of the dead with stunning works of art, and mocks death through caricature and comedy. Macabre is the common architectural style in Ozea.
Orcish currency is derived from glass beads. The art of glassworking is well beyond them, but perhaps the orcs have something of value to the civilized races, such as animal pelts, and well made axes, and bows. The humans trade beads for the goods, and the orcs will trade the beads amongst themselves as a form of their own currency. Perhaps they value blood red beads above all others, or animistic orcs favor beads in the colors of their gods.
Inspired by Indian trade beads, some of which could be quite ornate and beautiful. Most North American Indian beads were made in Italy. Surprise!
What if potions and tonics had negative side effects? Potions of increased strength cause violent tempers, or damage joints. What if potions of dexterity caused tremors, or palsy?
What if they were addictive, and had withdrawal symptoms?
Could someone make a bad batch? No one use the brown strength potion!
The Jiangsi was the name of an undead being in Chinese folklore and mythology. Usually translated as zombie or vampire for Western palates, the Jiangsi was really neither. They appeared as simply risen, fresh corpses. They moved (peculiarly!) by hopping rather than walking, and sought out the living to suck the Qilife force from their victims.
Perhaps significantly more interesting than the Jiangsi itself, was the lore surrounding them. "Zombie wranglers", or "Corpse Herders", usually Daoist priests, were men tasked with delivering these undead beings back to their respective home towns. Tradition in China placed great importance and emphasis on the return of the dead to their homes and families, and thus the corpse herders came to be. By using magick words and talismans they would animate the dead, and by placing specially inscribed parchments of paper over the Jiangsi heads and faces, the corpse herders would be able to control the hopping corpses. Then like pied pipers, they would lead processions of subdued undead, across many miles, rhythmically chanting and ringing tiny bells.
Special inns were built across China to house these undead caravans, as the zombies could only travel by evening and night, the sun anathema to them. Rows of doors opening to barely a closet-space, lined the walls of these special establishments. Behind these doors, the corpses would be stored upright while the corpse herders rested in rooms.
The Jiangsi under the control of a corpse herder were quite harmless, merely hopping after him, silently and without complaint, for weeks and months. If however, the magicked parchment would somehow be removed from their faces, the creatures would immediately seek living humans to kill. Their thirst for Qi was unquenchable.
The job of a corpse herder was an interesting one to say the least.
