(They have a worldbuilding page. Woot!) Elves are tall and fair with long blond or brown hair. They have pointed ears and their eyes are either blue or brown. They are nimble, and well, generally look like the ones in Lord of the Rings. However, there are differences. They are not immortal. Elves have an average lifespan of 400 years, making them the second longest living of Calhortea's races. They hail from the land of Olithea, which is forested. Their homes are a sort of cross between the Swiss Family Robinson tree house (from the book) and Lothlorien. The tree houses are entered by staircases carved out of the inside of enormous tree trunks. That concept in Swiss Family Robinson always intrigued me greatly, so I decided to include it. Their architecture looks very natural, as if it grew rather than being built.
They can do a lot of things, they're really no more limited in their types of skills than humans, but they are always much more artistic about it. And their nimbleness and sharp senses do make things better. They can fight, and even fought against the strytes when they took over Calhortz. That led to their population being all but wiped out, but anyway. Some of them are scholars, Camthalion in particular. They are not anywhere near the merfolk in terms of engineering, however.
I realized the other day that the elves behave very much like the people in the Elsie Dinsmore books. Which is to say, proper and old-fashioned and affectionate and...well, if you've read the Elsie books, you know what I'm talking about. The good guys, not the bad ones. I don't have anyone who is like Arthur Dinsmore, though I wouldn't say every single elf alive is good. They are fallen creatures just like everyone else.
Their names...well...some I made up and others I got from name generators. So there isn't really anything exciting there. Estranna came from a combination of Esther and Anna. Havilan developed from turning Calvin into Halvin and then remembering I had a Calvin and changing it up a little more. Camthalion came straight out of an elvish name generator. If I remember right, it's what George would be if it were elvish (according to the generator).
Elves play a very prominent role in Time Captives. Not much would have actually happened without them, for all the characters have to work together, whether they are Time Captives or not.
