Kithabel asks the nearest dragon if there are any other side effects of the Bond besides the love thing, creepy thought sharing business for a few minutes, linked-up proneness to death, and omnipotence.
"Excuse me?!" says Milan.
"I wouldn't either, but that's no excuse," says Milan.
"On the other hand, I think you'll be pleased to hear that losing one's last Bonded is not literally immediately fatal," says Saravasse. "It takes a few seconds, and if there's another Dragonbond Mage or two around and they're quick about it, the dying dragon can be saved before they're all the way gone and hang on until they find another Bondmate. But you have to be very quick, and this method was discovered at the same time as co-Bonding, which is a much more reliable way to keep dragons alive when our Bonded die."
"What else?" says Milan.
"...If I were you, as the only dragon in your universe, I would be very worried about accumulating more Bondmates," says Saravasse. "Are you very, very sure that you have only the one type of magic?"
"In Kithabel's world, yes," says Milan. "Mine has... more than that."
"Then if you return to your world - or hang around Milliways - and acquire any new Bondmates, I advise you to kill them immediately at the first sign of trouble," says Saravasse. "Considering that you can resurrect the dead, this should only be a minor inconvenience for them if it turns out that they weren't so bad after all and you feel safe bringing them back, but if they happen to be colossal idiots like my Bisochim they could do an enormous amount of damage before you found a less drastic solution."
"...I'll take that under advisement," says Milan.
"You do that."
"Does the control mechanism do anything useful like, say, let me forbid adding extraneous Bondmates he doesn't even want, or is it just creepy and horrible."
"What a delightful mental image," mutters Milan.
"I also advise consulting a unicorn if you're going to continue doing these sorts of experiments," says Saravasse. "A unicorn might be able to tell you things such as what happens if your Bondmates start playing keep-away with your free will."
"By all means, do send someone to fetch me a unicorn," says Milan.
"Please," agrees Kithabel emphatically. "A unicorn who can tell us such information seems like just the thing."
"Why?"
"Where am I going to find a unicorn?"
"Oh, I'll do it," sighs Atuona, and she takes off.
"Thank you," says Milan.
"I would prefer to avoid you causing some sort of horrible disaster," says Saravasse.
"So would we all, I'm sure."
"Hello," says the unicorn. "The Wild Magic says thank you for all these dragons."
"The Wild Magic is welcome. What's the Wild Magic?"
"It's like gods but better," says the unicorn.
"That's not a lot like gods," says Milan.
"Gods know fewer things than the Wild Magic, but can do more," says the unicorn.
"Okay, fair."
"So can you assuage our various worries about our possible course of action?"
"How likely am I to end up with an extra Bondmate I'll regret if I turn into a dragon? How horribly will it turn out if I do and Kithabel has to rescue me from them? What is up with the mental sharing thing? Will I in fact be able to resurrect Kithabel on the spot before succumbing to Bondmate loss myself if she ever dies? Is there anything else we don't know about and should?"
"That is a lot of worries. Just a moment," says the unicorn. He swishes his tail and closes his eyes and thinks hard for a bit, and then he says:
"You only Bond to people you're going to like and get along with and mostly you are only going to like and get along with people who aren't the sort of people who you'd need rescuing from because you are lucky and perceptive. It would be pretty horrible if she had to rescue you but it would probably turn out okay unless there was some other kind of magic involved that the Wild Magic has never heard of. You'd be a really young dragon so you won't do hardly any mental sharing at all. You are very fast and won't have trouble resurrecting your Bonded. You should talk to a unicorn before trying to do most things you might think of to do with this world's magic, but resurrecting dragons is fine and turning people into dragons is fine too. Once somebody is a dragon they can't not be a dragon ever again no matter what, so you should be really sure you want to be a dragon before you try turning into one."
The unicorn pauses for breath, then adds, "You can only be the thing that's like a Dragonbond but has to do with being sparkly while you are the thing that is why you are sparkly, but you're right that anyone who has a sparkly Dragonbond would get a real Dragonbond if someone involved turned into a dragon."
"...Noted," says Milan.
Kithabel giggles at this description of mate bonds. "But he doesn't want to be a dragon forever. I mean, I assume. And we just turned a dragon into a human and back again..."
"So being human-shaped is, for example, no refuge from accumulating more Dragonbonds?"
"Yes, exactly," says the unicorn. "And it won't make you stop being Bonded to your Bondmates or anything. You can change a dragon's shape but not their dragon-ness."
"The whole 'mesmerizing beauty' thing, if Milan just - turns invisible whenever somebody starts gazing at him too enthusiastically - will that work?"
"True," says Milan.
"Well, so much for that idea unless we plan on the use of my creepy control powers as a failsafe..."
"Won't catch me arguing with that," says Milan.
"But it's good that you resurrected so many dragons," says the unicorn. "...The Wild Magic says that if you're ever somewhere where there aren't any unicorns and you need to ask a unicorn about something, you can resurrect Tialle. I'm not sure why her specifically. Maybe because she's been dead for a really long time but I happen to know her name to tell you it." He pauses. "And it says it might want to send a unicorn to your world to get some of your magic and bring it back and Dragonbond with it. I didn't even know unicorns could Dragonbond but I guess if we had a kind of magic that worked for it we could."
"How useful."
"...And you can only get a Dragonbond if you do have a kind of magic that works, I forgot to say that part out loud when I was telling you about the sparkly Dragonbonds."
"How is the Wild Magic telling you all this?"
"It's because I'm a unicorn. Don't turn people into unicorns."
"And unicorns will definitely... work... even if we resurrect Tialle in another world or something."
