"I wonder why it didn't. Did you try scrying, too? Was there anything remotely informative about the way it failed?"
"Hmmm... if you knew someone who had an alternate shape that glowed, you could try scrying that... unicorns only glow sometimes, so that won't work. But there's creatures that glow all the time, I think."
"Any shapes? No matter what kind of creature it is or how they usually go about glowing? That seems worth investigating, at least."
"Could I petition the dragon council for experimental volunteers? Or - I bet I could find a unicorn spell that makes things glow and cast it on one of your shapes and see if you can scry it then. That would at least be a start."
"Does the dragon council not talk to people who aren't dragons? Why not?"
"It's species-relevant that you happen to be the only species that can deliberately turn into glowing creatures to be scried in Lialen - isn't it? Are you? It doesn't really get any more or less species-relevant depending on whether or not whoever thinks of it can find a dragon to talk to the dragon council about it for them, anyway."
"I mean - yes, it is species-relevant that that, but they're not set up to take requests from non-dragons. If you want to talk to them about something dragon-relevant you go through a dragon, and I don't want me and my dragony-ness too close to Lialen theory. They figure if you can't find any dragons to pass up the message it can't be that important."
"That's very silly of them," says Blueberry. "But I suppose I'm not likely to convince them of that. Anyway, a glowing spell shouldn't be too hard, I'll look one up when I get home. Ideally one that stays on once it's cast and doesn't need active maintenance, but can be turned off afterward. It would probably be inconvenient if you just went around glowing forever."
"A little bit. I mostly just use my dragon shape to fly and breathe fire occasionally, it wouldn't be that big a deal, but yes, one that you can turn off would improve the situation. When you're home can you also look up that stuff about other creatures turning into unicorns? Dragons don't get species-specific magic from, say, vampires if we turn into those, but since their magic is also shapeshifting it's hard to be sure why."
"Yes, I'll do that too. Are there wizard spells that - oh, but they'd probably break when you switched - hmm. Do wizard spells on people break when they switch shapes?"
"Hmmmm. What if you cast a spell on a specific part of a person? Like, I don't know... making the end of your nose glow?"
"Sometimes that'll fall apart - oh, you know what's a good example of that, there's this ultra-basic one-trick spell called the Lanfen trace, it makes the tip of your right forefinger leave a glowing white trail wherever you move it until you reverse the spell. If I shift while that's on, my natural form doesn't have fingers per se and the spell breaks."
"Aha. Hmm... actually, you said you could take objects with you, what about if they're glowing objects?"
"Yes. And you can do different kinds of glowing things. Does fire burn in Lialen?"
"That seems pretty conclusive," she giggles. "But if you tuck a non-fire lamp that's on and then bring it back does it still... lamp?"
"Waterspouts spout water?" she guesses. "That's interesting. Is there a way to find out if it was spouting while it was there?"
