/tg/ give me all your fictional metals and elements! Post their

I sometimes toy with 'madjrium', chemical symbol Mj, in settings that have magic. It's a thaumoelectric metal--push a magical gradient across it, and it creates a voltage. It also has a distinctive purple sheen, the same way that gold is yellow or copper is red-orange. The only big problem with the stuff is that it's radioactive, with a half-life on the order of a few million years, due to having an atomic number of 126 and island-of-stability optimists winning the lottery.

I don't have a name for it yet but it's a green rubber substance that is able to pass through itself. This allows for doors that require suits of the same materiel to pass through.

If it can pass through itself, how the fuck do you make anything out of it?

Stolen from the Witcher: Dimeritium, basically acts as lead but for magic.

I'd assume if you were to forge/carve/prepare/temper it in some certain way it would maintain form and become a single "unit" of the element.

That's just an idea though, I have no fuckin clue how anon was gonna run that.

>there's literally no limit to how much of it can pass through itself at one time
>the big bad's plan is to put a cone-shaped vessel under a city and use a portal to continuously pour this stuff in until it creates a singularity

Ultonium, a nanite-derivative programmable smart-metal that is as light as Microlattice but stronger and more durable than diamond. Its bulk modulus is extremely high, in the 950 GPa range; hence everything from individual soldier's armor to space dreadnoughts are made out of it.

Ichor

After preparation it will bond with the first solid object it touches, suffusing it and giving it a slight appearance change - soft glow, bright 'veins' of color, a sheen that doesn't appear when you look directly at it.

Ichor was developed to get around the restriction that mundane materials can't be enchanted. So you enchant the ichor, and then introduce it to an item you want to be enhanced.

Works on living creatures too, but there are always side effects.

It's a reddish ore that turns dirt-colored when wet. It's usually found in swamps, making it a rare thing to find without some earthquake shenanigans going on.

It has weird properties that master smiths can turn into magic items. Usually, this means "Shit can catch fire when you swing it," or "Bro, it's freezing cold to the touch," or "Goddamn, it just keeps bleeding acid, what the fuck." My players usually fall over themselves to go after it, even if they're covered in magic items already.

I call it Delirium, because every time I try to name it something else, my group defaults to that.

A gel like substance with variable levels of viscosity and can achieve temperatures of lava or freeze solid quickly.

The idea was that Dwarves invented it to help them in their forges and act as a sort of defense system as well making certain rooms and areas inaccessible by literally turning the floor into lava.

Tell me more.

I like my Master of Orion, so my strong and light metal is called Tritanium (because it's 3,14 times stronger than Duranium, of course), then there's Sorium used for conventional engines and harvested from gas giants. Then of course Anti-Matter for FTL jumps.
