She stares at him openly for a minute, then nods. "Right, so, 'all evil gods'. I suppose that narrows the list down to one-third, at least. A start. And we know it's most likely a deity, and not a mortal, then, which narrows it down further." She sits back, stroking one of her tails, as she thinks. "Sounds like a custom-made item, for this purpose; I don't think there's much value in weapons that only explode a week after being activated, unless this sort of thing is more common than I imagine it is.  And it's been... a month since you issued the challenge, so whoever made it likely worked quickly. I'd start by checking the major weapons crafters of the planes, since only a specialist could craft a weapon like that quickly enough. Or a deity with crafting abilities, I suppose... I'm not sure what the limits are, but I think some of you can just snap your fingers and make something like that. Figure out which ones can... but rule them out. They'd strike sooner, and likely more spectacularly than that."
