Okay, but, and this is all speculative, but I have a theory: whoever talks to us for long enough, if they're smart enough, notices that we're going to radically transform the setting. Most people haven't spoken with us long enough to notice, or, uh, they aren't - I don't want to say that they aren't smart enough but they lack the prerequisites and they don't have enough chunked to compute it all in one sweep, so they think about little things like eradicating malaria and don't leap to the generalization that Earth technology opens new opportunities to start reactions which create their own reactants... um, backing up a step, let's just say "we know about Earth technology" because that's already a big thing on its own. Most people don't have enough chunked knowledge to understand what it means.
And, on this theory, the reason for all the divine interest in the Vault is - us. The four of us.
Maybe Otolmens noticed first... maybe because I was thinking things which put me in the right state of mind, like it says in the setting document can get a god's attention... though I'm not within an alignment step... or maybe Ragathiel gave her heads up, as part of an ancient commitment or something? Or maybe she's just good at noticing things or has ways unique to her among the gods. Anyway, the theory continues that other gods noticed her noticing, when she pulled the flashy miracles, but didn't necessarily notice what she noticed. So this is Asmodeus trying to figure out what weird thing is going on.
And we shouldn't make that easy for him.
