Klahan

I looked at the purple medallion in hand and immediately became surprised. As I had thought it to be metallic, but it had turned out to be crystalline.

There is no text on it, but a simple design of three globes, similar to the three moons hanging in the sky.

I stared at it for a moment, before you sent out my vitality, soul energy, and inheritance energy inside it and immediately felt it imprinting it. 

I did not get a memory packet from it; it had just imprinted my energies. When I investigated a little, I felt it was impossible to remove my signature from it, and that couldn't help but make me relieved.

It wouldn't have been a reliable id if a person of my power could wipe the signature from it.

Buzz!

I inserted my energies again, and this time, a change occurred. It buzzed and the projection of three moons appeared above it.

The moons looked like the moons in the sky.
