Another characters with names starting with 'A'. Pretty interesting chapter in form of background. I never thought they would have underground system like this. I liked how it was advanced technology yet with old-school feel (the organ and pipes), I really enjoy this non-tech flavour Aqua has. And guess we aren't seeing Al for the last time.
But now I'm curious about their ageing - if Mars orbits the Sun twice as long, doesn't it also mean one year here equals two years on the Earth? Wonder if this will get ever explained.
