At some night (of your choice) in the future, Yuri will feel a wind approach him. No voice will come with it; however, after a moment, he will begin to feel an intense pain in his forehead. This pain should only last a few minutes, though, and once it is done he will have both the gem and his new powers.

Whenever he goes into Dyster, the cultists will be awe-inspired by the gem, and tell him how blessed he is. Additionally, if you would like, the gem can "activate" and glow intensely when he uses his power. (This is entirely optional.)
