In the background of the Northern Arcadian novels is the threat of invasion from another world, from creatures I have variously dubbed ‘wyverns,’ ‘worms’ and ‘dragons.’ Today, though, the affair is settled, thanks to an extremely interesting (and dubious) article about a proto-language dubbed ‘Eurasiatic.’ The hypothesis is based mostly upon the discovery of multiple cognates (words that sound the same in different languages) for a core vocabulary that includes… ‘worm.’

If you’re trying to sell the notion that, once upon a time, all of mankind had a shared enemy in the great and terrible wyverns dragons worms, this is the kind of thing that makes your story stronger. (And also makes your day.)
