CuSith

It gets its name from the Scottish mythical creature the Cù Sìth, a bull sized creature that resembled a dog. It is said to lead people to the afterlife. It is also said that it would wander the Scottish Highlands, occasionally letting out three extremely loud and terror inducing barks that could be heard from miles. If you were unable to escape to safety by the time it barked for the final time you would be so overcome by fear that you would die
