Magic Draining

A recent breakthrough in engineering and research led to the development of magic draining, a technology which allows dragons to drain magic from another dragon. Originally developed as a way to safely imprison magic-capable individuals, the ability to store magic in a way that lets anyone use it has enormous potential. For now, the technology is still newly developing, and sees little use even as a restraint, but according to many, magic draining could change the world forever.  

Discovery

For a long time, research into magic and magic use has been a hot topic among dragons. Especially important is ways to stop it, to reduce one's ability to cast magic after they're already trained. Most cultures which believe in prisons and lock-ups to punish law-breakers rely on especially heavy punishments when the dragon in question is capable of magic, as a well-trained caster can weave magic with a single twitch of a finger or a soft-spoken word.   Finding more humane ways of dealing with this is important to many. A breakthrough in how to sense magic with technology allowed these researchers to use it specifically to tap into the magic inside a dragon's body, and with that, find a way to remove it. Temporarily, anyway.
