Kanimir is, as he often is, sitting in his library enjoying a book on magic and pondering theoretical innovation. He has an idea; he writes it down. It probably won't pan out, most of them don't, but it might.
"Hybrids are elementals who are two elements. Penumbra's both Shade and Shine and can do all the magic either can do, although she doesn't have twice as much total magic to do it with."
"Is the name inherent?"
"Yeah, they coalesce knowing what kind they are. I guess she doesn't have your language so she might or might not endorse the translation."
"Hm. What are the names for the other kinds of hybrids?"
"I don't know them all and they might not all have ever happened. Mist, Rainbow, Silver, Amber, Leaf, Ash..."
"Air and water, shine and water, no idea, wood and something, wood and something, wood and fire?"
"Yes, yes, Adamant and Lightning, Wood and Glass, Wood and Earth, yes."
"Silver. Not what I would have expected of that combination."
"What would you have expected?"
"Huh. Adamants can do magnet stuff alone, what would Lightning have to do with it?"
"Oh, do they? Well, lightning is the natural form of a phenomenon called electricity, which is strongly connected to magnetism--either can easily create the other."
"Huh. Maybe a Lightning/Adamant elemental would have neat synergy."
"That would be interesting!"
"Unfortunately I've never met one!"
"Pity. On the other hand it seems it would be--patronizing--to go out of one's way to meet at least one of every kind."
"There might not be all the hybrids."
"I'm not sure they'd object to the motive, though, especially wild ones."
"Mm. I'd still want to be careful, but that does make it better."
"Wild elementals are cute."
"I mean, I've never met one in the wild, but the way they talk about how they were before they met humans sounds cute. They do stuff like stand under waterfalls playing with the water and tasting random things to see what's food and they fly around and they've got nowhere they need to be or anything they need to do, they haven't picked up hangups and anxieties about civilization-style stuff..."
"That does sound cute."
