Cam is dipping a grilled cheese sandwich into a bowl of tomato soup when he feels the summons. He goes ahead and grabs it. Doesn't even drop the sandwich.
"I like mine better. But with one or two assumptions this one can probably be brought around."
"Oh - at home only humans can summon. I don't know if that will hold here, because your non-humans aren't daeva."
"You can't eat solid food and have to drink blood, but your taste buds aren't actually reconfigured. Garlic smells terrible. Maintaining a diurnal schedule is a pain and requires heavy clothing and parasols. You're a little stronger than a human but not much, depending on who you've been feeding on."
"Sounds inconvenient. I'd do it too to not keel over of old age, though, if that were something that could happen to me anymore."
"Oh, that's nice. Daeva have that too. I actually looked like this when I died - minus the wings and the tail, I made those - but if I'd been old I wouldn't have looked it when I appeared in Hell."
"Well, for all I know they'd keep the inconveniences, at least to a point, but a volunteer experimental subject is a useful thing to have. After we get rid of this guy and I handle the emergency priorities that I shouldn't risk leaving forever without handling."
