Well, I guess you could call the earthpulse and whatever storm that was passing over at the time parents... but not really. There probably were and are other seraphim who formed at that point, but they're kinda just other people to me. But some seraphim do think of others as siblings, I've known at least a pair.

... I probably should'a stayed away from body analogies, huh?

As far as I know, no? The world does just fine in areas we don't live in. And the Lords mostly stick about keeping their blessings in place so.... our version of the starscourge doesn't get bad. [ OOPS... the topic they were avoiding... ]
