Unobyiffium

Unobyiffium
Unobyiffium is a rare ore in the universe, only found natural on a few worlds across the universe. It doesn't make for a paricularly good crafting material and is often left unused once a culture discovers iron.

It does however have one unique property that makes it extremely valuable and unlike any other substance in the universe.

When a Furry comes in contact with the ore they will be overcome by an uncontrolable need to 'Yiff', an act of exploding 'liquid joy' everywhere. Strangely the mineral is used up in this process, reacting with the furry's body in some way that causes this reaction.

Once a furry has experienced a 'Yiff' they become adicted to the sensation, obsessed to experience it again and again. Which makes this ore extremely valuable to those who've experienced the Yiff, like a drug that they will do anything to get.

Because of this a merchantile collective called the Fur Federation has cornered the market on Unobyiffium, taking all known sources of it and charging a conciderable amount for it. Making them the wealthiest corperation in the universe, and pushing them to find more and more sources of the ore no matter what.

Trivia:

-Unobyiffium is a parody on the movie 'Avatar' and it's ore called 'Unobtainium'.
