From the Department of Interestingness:
Just found out about these 5000 year old crystal weapons archeologists found in a series of megalithic tombs in Spain.
They found the remains of 25 people inside the tombs, and it is believed that all of the people owned the weapons collectively, meaning that they did not belong to one individual specifically.

Okay, now I want to incorporate crystal weapons into a character design, or figure out how to fit it in one of my stories.
