Also, some neat magical materials in setting
Mithril- light, sharp. Only found in secret dwarven mines, or created through Sabrielist void magic.
Thunder Bronze - Normal bronze, but it can collect and generate electrical energy, which can be unleashed as bolts of lightning or auras of electricity, power equal to the amount of metal, though bolts need special engineering. Dwarven only. Used by dwarves for their Lightning Pikes.
Burial Iron - Ancient iron held by the dead for centuries, infused with the Death Rune- instantly kills anything it grievously wounds, and badly damages the undead- downside it actively sickens and weakens the wielder. Mostly just used by the Triarchy, a reviled and reclusive civilization of nomads ruled by urban undead dwelling in great necropolis (necropoli?).
Deep Copper - holding the appearance of copper, this metal is actually distinct, being as hard and strong as iron, without it's brittleness. Very useful for earth magic, otherwise unremarkable. Found only far, far underground.
Enchanted Lead- normal lead put through rituals done by trolls- this metal actively darkens the area, and is as hard as iron or bronze while being far heavier. The preferred weaponry of trolls, and the sole metal of deep troll equipment.
Dwarven Quicksilver- Mercury given a sort of base sentience- obedient to its handlers, it has strange healing powers, and can create lethally sharp pseudopods. The Emperor wears a cape made entirely of this metal, which has stopped many assassins. Only creatable by Imperial Dwarven Alchemists.
Serpent Spine - Weapons and armor made from massive serpent fangs. Not terribly strong, but all drip potent poison, and the fangs made excellent puncturing weapons. Used almost exclusively by the Poisonkin tribes, whose tainted physiology has little to fear from being constantly covered in noxious poisons.
