[Game thread] Skull Ruins Pokerole

[Iron]

Heart and Angie dig around the old campsite marker. They find an old trash pit full of pottery shards and broken fossilized apricorns, but the only useful thing there is a thumb-sized chunk of Meteoric SuperConductor.

However, Angie eventually uncovers a limestone sinkhole or underground cavern. She breaks right into it, and invites Heart inside to see what she's found.

What has she found? She's found a well-preserved chunk of the campsite, where the air has been still for so many centuries. There's a few petrified stumps around a campfire ring, which still has remnant ashes. A faded cloth seems to be a collapsed tent of one of the officers. He may have left in a hurry, for you find three empty chests and one smaller chest that rattles when you pick it up.

Inside is an ancient artifact! It looks like a hexagonal gem, but each facet is a different color of the rainbow. It's set into a circular zinc plate on straps. It's designed to strap around a person's torso like a reverse backpack.

Heart's not sure what it is. This item appears to possess Earthpower akin to that of Mega Evolution...but it's not a Mega Stone or a Key Stone.
