I think ethymologies in each race trivia is not junk, since it's give information about the race name's history and background. This background can help people while reading the novel to understand the race characteristics better.
In most of game/anime's source of information (wikis, forums, etc) I know, if the author consist of mythological races like this, a such trivia (ethymology, history, background or such) will be included, simply to give more explanation for the reader.
Due to this reason, I'll repost all the ethymology trivia to all pages, although the rest trivia will still be deleted.
I do think most of the races in ALO are based on some myth and legends, and it's do have some relevance, especially on their base attribute. I'll do some further research on this topic, and later if I found out the whole answer for whole ALO races, I'll put it in a forum page, as well as update the trivia section.
But for the time being, I'm away for the New Year's holiday and miht be back around 2nd or 3rd of January. I probably still be back daily just to check what happening here.
