Dude, it's roleplaying. It doesn't need to make sense. It's like Pokemon and Yugioh. How the poop do creatures fit in these magical red and white balls/how do monsters come out of cards. These discs are flat, small symbol thingies that have a hole in the middle, so I called them disks.

What kind of name is Technomancer Greene?
Kewpo.
It's a name I've grown to love. It's a variation of "kupo", a saying Moogles would say in the Kingdom Hearts series to Sora. Who honestly judges names? A name is a name. I'm naming my kids names no parent ever named their kids. Cry and die about it. He's still human.

Is age really that important? If you write down an age, say 15, the next year he would be technically 16, but in like an anime or something he's still be 15. Ash Ketchum is like "20 years old". You just need to known he's a teen.
