Shining Crystal

The Crystal ball is emitting mysterious power.

Beside the crystal ball, you find faded patterns marked on the floor.

Looks like some kind of keyhole that needs to be inserted with something...

The blue key suddenly responds once you come close to the keyhole.

You insert the key in the keyhole and it turns out to be a small gem.

When you touch the gem which is dazzling blue....

Someone's sobbing comes into your ears as you smell blood on the wind and suddenly you become angry.

You have found a Blue Charm Stone that is concentrated with grudge and mysterious power.

Something is definitely there inside... How do I get it to open?
