Halfling slave #958245 "Broom" has never heard of Otolmens, which was obviously going to be true in retrospect, and doesn't know what this whole project is about, which was also obviously going to be true in retrospect, and doesn't have much of an education, of course, and has not received any helpful revelations from a primordial inevitable who would have a harder time talking to him than even Asmodeus would, of course, and is having a hard time understanding what is even going on at all, of course, let alone why the Grand High Priestess of Asmodeus would be trying to have a plainly spoken discussion with him, of course, and Aspexia could no doubt have foreseen this herself if she'd spent an additional minute thinking about it in advance, of course.
Aspexia keeps her temper under absolute control. When she gets home for the day - if, indeed, she ever does get home for the day - she's going to order a dozen slaves sent to her, bask in their understandable fears for a while, and then set all of them on fire.
Why. Why did Otolmens pick him. Why halfling slave #958245?
...because Broom is a simple predictable mortal, who will do something predictable in the future, if Aspexia had to guess.
All right. Aspexia will not modify her predictable initial plans unless Asmodeus tells her to. Broom gets a greater invisibility ring and a dagger of assassination; and what Aspexia hopes is exactly the right level of gentle suggestion not to kill random Asmodeans without a reason, and that the reason is supposed to have something to do with his new god and Her purposes, not just Broom's previous grudges...
Aspexia is glad that she doesn't have to work on this project or live in this villa, but, in fact, she doesn't have to work on this project or live in this villa, so everything is fine.
