Féar Gortagh/Fair Gortha/Fear Gortach/Fod Gortach/Fairy Grass/Hungry Grass
The Féar Gortagh is from Irish myth. It’s thought to be a patch of grass where someone died a violent or unnatural death, though it is indistinguishable from any other grass. It drains the life force of its victims, with them sometimes dying if they don’t immediately eat or drink something. Some believe that any who step on Fèar Gortagh becomes so hungry they eat themselves.
