"You're welcome." She sort of declines to keep standing, so she sits. Floating. In mid-air. Because there's no chair. "Right, so, I am not a summoner, and have never been one. So I don't actually know the whole - logic behind making bindings. I could not make a solid one; only copy bindings that I've seen and remember clearly. I could make a reasonably solid non-terrible fairy binding, but the bindings for the different daeva require different things. And the two for changing-daeva that I've seen and remember anything of were not the kindest bindings ever. One didn't let the daeva change any matter connected to a human - which would prevent healing of any sort - and the other was highly restrictive about things the daeva could do. It's why I remembered it at all, the daeva I worked with bitched about it being terrible, so of course I looked at it.

"I could prevent him from, say, killing you, but that's not the danger of a daeva. The danger of a daeva is if one you summoned put you in a coma, then took you to - I don't know, the Moon, and then put you on an IV drip for the rest of your life while they go do whatever they want. And I can't prevent that at all. ... I mean I could switch this up to a fairy summoning, but another my-set-of-powers won't scale as well as having multiple types of daeva. And summoning a fairy wouldn't erase the danger of summoning other daeva, and all of the fairies I know don't like to work long-term and expect to go home in an hour or two, and we haven't proven that daeva can be unsummoned here, and I really do trust my friend."
