Small black flying creatures that travel in swarms appeared in The Forgotten Echo. They are described as looking a bit like a horsefly but black and spikey. They live on top of certain windmills and are strong enough to make a hole in a skull.

The Forgotten EchoEdit

An unkown swarm of flying things attacked Tom and G.F. Moore as they tried to get to the Monestry where Sir Henry Scatterhorn and August Catcher was. Lotus also said she was attacked.
