Hellhound (Rare Summon)/Origin

Origin 1
Hellhounds are supernatural dogs found in many myths. They are similar to uniquotious dragons. Some say that if you stare into it's eyes three or more times, you will die. They often guard the entries the the world of the dead and have fire based abilities. Some say that it's howl is an Omen of death or brings death. One example is Ceberus, found in Greek mythology.

Origin 2
Barghest, Bargtjest, Bo-guest, Bargheist, Bargeist, Barguist, Bargest or Barguest is the name often given in the north of England, especially in Yorkshire, to a legendary monstrous black dog with huge teeth and claws, though in other cases the name can refer to a ghost or household elf, especially in Northumberland and Durham (see Cauld Lad of Hylton). One is said to frequent a remote gorge named Troller's Gill. There is also a story of a Barghest entering the city of York occasionally, where, according to legend, it preys on lone travellers in the city's narrow Snickelways. Whitby is also associated with the spectre. A famous Barghest was said to live near Darlington who was said to take the form of a headless man (who would vanish in flames), a headless lady, a white cat, a dog, rabbit and black dog. Another was said to live in an "uncannie-looking" dale between Darlington and Houghton near Throstlenest, and yet another haunted an area of wasteland between Wreghorn and Headingley Hill near Leeds.

Besides taking the form of a large black dog with fiery eyes, it could also become invisible and walk about with the sound of rattling chains. At the death of any notable person the barghest would appear, followed by all the other dogs of the local region in a kind of funeral procession, and begin howling and baying. It may also foretell the death of an individual by lying across the threshold of his or her house. It is sometimes said that like the vampire the barghest is unable to cross rivers.

The derivation of the word barghest is disputed. Ghost in the north of England was once pronounced guest, and the name is thought to be burh-ghest: town-ghost. Others explain it as German Berg-geist (mountain spirit), or Bär-geist (bear-spirit), in allusion to its alleged appearance at times as a bear. Another mooted derivation is 'Bier-Geist', the 'spirit of the funeral bier'.
