Petrified Shores
You stumble across a peculiar crystalline beach off the coast of a mysterious lake. A calcified lake-shore of weathered iridescent stone. The appearance seems almost man made- however, the only thing here that's man-made seems to be a storage area. It is guarded, and upon closer inspection the guardian speaks to you.
"Welcome Traveler, have you come to take a peek at my wares? Oh no no, they're not for sale. They're all just here for show." They appear to be a hoarder, a pack-rat of sorts with all kinds of baubles and knickknacks they wish to show off.
