Nieldun is unsurprised at this confession of Archy's terrible parenting instincts and destructive urges. He was however surprised that Archangels were even worth mentioning as a weakness. Sure, his religion taught that angels of both light and dark served the gods for good or ill but surely there were none here? Now, that detail about the Archdemons mating habits was interesting but not quite useful yet. Now, as for weaknesses, wounding the other Archdemons would be possible with Stygian Iron (though the Shadows were probably too scared to help) and Shaan Tzien had a dragon but one dragon and Archy against Nine were not odds he liked. "Can't you slay other Archdemons permanently as well? Other than the Tzieni dragon, do you know of any of those three that might be easily found? What about the lesser fiends, what are their weaknesses? Do they fear anything?"
