We know that Mhach summoned a host of voidsent, and in particular Diabolos, in their war with Amdapor. But everywhere we look in Amdapor (the areas we can see), it looks a whole heckuva lot like Amdapor was summoning Sineaters to fight them, maybe as a last-ditch effort?

Is there any lore to this? I'll admit this is based primarily around the dungeons, but it seems a little past coincidental that the bosses are a giant white-marble lion and a giant white-marble angel.

I don't think I'm bring clever here, I'm asking if anyone's seen or heard anything official that disproves or proves it.
