Lore

Gwyllgi, the "Dog of Darkness," is a fearsome black hellhound in Welsh folklore, larger than any normal dog with blazing eyes. Roaming lonely roads at night, it brings terror, misfortune, or death to travelers— a spectral guardian or harbinger akin to other British black dog legends in Celtic tradition.
