Aionios = the Greek adjective for age-during. A word of which there isn't really an equivilant in English. Probably 'temporary' would fit.

I like it because that's what I am, 'aionios'. Everyone is aionios. We all belong to the age, we all are born and we all die.

The irony is that if I were to inherit eternal life then I wouldn't be aionios anymore, I would be 'aidios'.

But I don't care, it's still a cool name.
