4 of them destroyed everything, they killed all my animals and I couldn't do anything to stop them, they attacked a remote base where I had the pigs ... am I supposed to dig a pit around all my bases increasing the video-lag? And how am I going to take the pigs inside of the wooden fence area later? it's really too annoying, it's just not fun, you never have enough stamina, most of the time it's dark, and now hordes of Fulings ...

This event has been in the game since the beginning. You unlock that horde event by defeating the dragon boss Moder.
