hc that the angels are all born in specific generations. Each gen gets a little more advanced, a little more altered as the Arch kinda evolves its children. Maybe every time one of them dies it analyzes their life/how the died and makes adjustments based on that?
Gen 1 is of course the Archangels.
Gen 2 has maybe 25 angels? 5 for each Arche. Includes Urzael, but none of the other lieutenants.
And from there the gens get exponentially larger.
Anyway the only reason I'm even thinking about this is cuz I like thinkin about how everyone Inarius knew and loved is dead, either killed by the war he desperately wanted to escape, or by his wife after he pushed her to the brink of madness.
And I was thinkin' it'd be just the cherry on top if he was the last angel from his gen alive. I guess it'd be kinda like being the last person from a graduating class standing.
He's probably pretty high up, coming out pretty quickly after Tyrael. Gen 2 or 3.
Although it might be even worse if he's like. Gen 56. And still the hundreds of other angels who came out of the arch with him are all dead.
Not to mention the mild existential horror of having your friend die and then meeting their replacement. They are eerily similar. Down to name and mannerism and what they do. But they look just different enough to be uncanny, and of course they don't remember you at all.
And this has also happened hundreds, even thousands of times, to everyone around you.
Actually the longer I think about it the worse the whole 'arch replacement' system gets.
