The púca (Irish for spirit/ghost) is primarily a creature of Irish folklore. Considered to be bringers both of good and bad fortune, they could either help or hinder rural and marine communities. The creatures were said to be shape changers which could take the appearance of black horses, goats and rabbits #folklore
Balor In the Celtic-Irish mythology, Balor is the god of death and the king of the Fomorians, a race of giants. Balor had only one eye, which he kept closed because anything he looked at would die instantly.
