Question about the dragons and their ages

Hello.

2 quick questions about the Aspects (original ones)

1. Does someone have the source for the 'Malygos was the oldest' (haven't read Dawn yet, so if it's there that's on me)
2. Do we have confirmation to 'Malygos being the oldest' does, in fact, NOT translate to 'yeah, in human years he's the only one legally allowed to buy booze'?

(this is not meant as snark, I'd genuinely like to know if there's Word Of God that Titans didn't just leave the world in the hands of a bunch of teenagers/young adults)
