Random idea for a D&D or similar "cursed" item:

The Ring of Curse-Bane
A simple ring with the inscription "I cannot free you, but I hope to spare others"

The ring is magic, but otherwise inert on it's own. However, when the wearer also is subject to another cursed item, this ring forces them to make a save to be able to part with a cursed item even momentarily (this is in addition to the typical check a cursed item usually forces). It makes the wearer more blatantly obsessed with any cursed items they carry as well.

If the wearer dies while subject to a curse, their body rises as an undead with the sole purpose of protecting the cursed item from being taken.

I imagine it being originally created by a magical prodigy who encountered a curse but didn't have access to the means to break it... so made an item that basically amplifies and feeds on a cursed item's power to prevent the curse from being passed to anyone else.

The increased obsession can be helpful potentially as it makes it much more obvious if you've been cursed, and if you can't be freed from it then it at least makes it less likely the curse will affect anyone else.

Random fiction world building idea:

Playing off the concept of "What if dragons aren't greedy but instead there's a benefit to them to make a nest out of gold?"

A world where dragons sleep on gold coins because it is a soft metal (coins because chips slide around and maybe help with molting?).

Easy start, but adding more to it: what if because of their bodyheat, weight, firebreathing, and scales they grind down and compress the gold as time passes. But then it becomes less comfortable, kinda like an old pillow that becomes flat.

What if they happily exchange chunks of this compressed gold for new gold coins?

So I'm imagining a world in which people get compressed gold from dragons and carve it into coins and distribute it. But then as the coins get handed around over time, they start to wear and resoften, and when too soft they get exchanged at the dragon horde again for a new compressed coin.

Economy as an ecosystem!

(Also Dragons obviously hate the 1% because they horde the gold without any real need, like if someone was causing a pillow shortage out of greed)
