Corundum Crystal

"Corundum crystals are shards of what was once a large magical monument built by an ancient and unknown culture. In an effort to determine its true purpose, a group of wizards attempted to activate the structure with a spell. The spell caused it to shatter with a massive explosion of energy, creating the Scar of the World in the process. These flawless crystals are all that remain of the monument."
