Not much, actually.

Your rewards: a few loaves of bread and a skein of water. An odd crystal too. With your meagre findings stored within you cloak, you trekked back up the mountainside to your cave. Once within its safety, you Observed the strange blue shard.

Claimant Crystal
An item that allows the user to claim a plot of land as their own. On this land, they have free reign to place, craft, build, and set rules. All players obtain this item at LVL 3.

So a Claimant Crystal, as the blue shard was called, allowed the user to claim an area as their own? And they could craft, build, destroy, etc. inside of it. Why? Why would you need it to do that stuff? You tried to break a rock nearby, but an error message popped up.

ERROR
PLOTNAME: BREAKSTONE_MOUNTAIN_CAVE IS NOT CLAIMED
CANNOT EDIT WORLD ON UNCLAIMED LAND

Ah. You decided to try to use the crystal, if only for shits and giggles. You held it up and formed the intent to use it. It shattered into a million particles that formed a screen.

Plot Cave on Breakstone Mountain is unclaimed. Would you like to claim it as yours?
Yes
No

Of course.

ERROR
CLAIMING ENTITY HAS NO NAME
PLEASE ENTER A NAME

Huh. You needed a name, apparently.
