Manoa Falls Trail: Mānoa Falls Trail is a 1.6 mile trail on the island of Oahu in Hawaii.  The trail is a part of the Honolulu Makau Trail System, and leads to a popular 150 foot waterfall called Manoa Falls.  Hiking the trail is approximately a one-hour round trip.  Many tourists are attracted to the waterfall and scenery throughout the trail.  The trails have a history as one of the earlier Hawaiian trails.  There are many legends of the Night Marchers, or ancient Hawaiian warriors associated with Manoa Falls.  Scenes in movies such as Jurassic Park and Catching Fire were filmed at Manoa Falls.  The Manoa Falls trail harbors many native Hawaiian plant species and tropical birds as well.  The Lyon Arboretum, located in the Manoa Valley at the base of the trail is another popular tourist attraction and aims to preserve endangered Hawaiian plants.  Rain showers are very common in on the trail and the path to the waterfall is often muddy and slippery.  Flash floods may also occur at any time.  Swimming in the pools of water on the trail is highly discouraged due to the threat of Leptospirosis.

The Book of Ceremonial Magic: The Book of Ceremonial Magic by Arthur Edward Waite was originally called The Book of Black Magic and of Pacts.  It was first published in a limited run in 1898, and distributed more widely under the title "The Book of Ceremonial Magic" in 1910.  It is an attempt to document various famous grimoires, explain the history behind them (refuting many of the legends surrounding them), discuss the theology contained therein (e.g. raising the question why good angels would be summoned to kill an enemy), and to synthesize many famous grimoires into one system.

Paltinul River (Capra): The Paltinul River is a tributary of the Capra River in Romania.  It is one of the biggest rivers in Romania.  There are many legends surrounding it including the one of the Lizman.  who is supposedly known for snatching and eating children.

The trail leads up to the 150 foot waterfall.  Swimming in the pool below the waterfall is highly discouraged because there is a threat of becoming infected with Leptospirosis.  This disease causes mild to moderate flu-like symptoms that can last for up to 1 to 2 weeks.  Many tourists are attracted to the waterfall and the scenery throughout the Manoa falls trail leading up to it.  Another attraction near Manoa Falls is the Lyon Arboretum.

The waterfall and surrounding area experiences rainfall almost everyday, and flash floods are also possible.

Tree of Peace: The Iroquois Tree of Peace finds its roots in a man named, Dekanawidah.  The legends surrounding his place amongst the Iroquois is based in his role in creating the Five Nations Confederacy, which consisted of the Mohawks, Oneidas, Onondagas, Cayugas, and Senecas, and his place as a cultural hero to the Iroquois tribe.  The official title of the confederacy is, Kayanerenh-kowa (the Great Peace) as described by Paul A. Wallace, “it is also known as Kanonsionni (the Long-House), a term that describes both its geographical extent and its constitutional form.”  The myths and legends surrounding Dekanaweidah have the roots in the oral histories that followed many Native American tribes throughout their histories.  As Anthony F.C. Wallace stated, “The Dekanaweidah myth analyzed that may have been the projection of an Indian prophet’s vision.  Undoubtedly popular imagination has contributed much to the growth of the legend over centuries of oral transmission.”

Æbbingas: Abingdon and Abingdon Abbey were founded in Saxon times, possibly the 7th century.  The early history of Abingdon (and its abbey) has been distorted by the numerous legends surrounding its history.  The legends were invented to raise its status and explain the place-name.  The name seems to mean 'Hill of a man named Æbba, or a woman named Æbbe', possibly the saint to whom St Ebbe's Church in Oxford was dedicated (Æbbe of Coldingham or a different Æbbe of Oxford).  However Abingdon is actually in a valley and not on a hill.  It is thought that the name was first given to a place on Boars Hill above Chilswell, and the name was transferred to its present site when the Abbey was relocated.

Nightmarchers: In Hawaiian legend, Nightmarchers ("huaka'i pō" or "Spirit Ranks," " 'oi'o") are the ghosts of ancient Hawaiian warriors.  On the nights of Kane, Ku, Lono, or on the nights of Kanaloa they are said to come forth from their burial sites to march out to past battles or to other sacred places.  They march at sunset and just before the sun rises.  Anyone living near their path may hear chanting and marching, and must go inside to avoid notice.  They might appear during the day if coming to escort a dying relative to the spirit world.  Anyone looking upon or seen by the marchers will die unless a relative is within the marchers' ranks- some people maintain that if you lie face down on the ground they will not see you.  This is to show respect.  However, if exiting the area is the fastest option, it is recommended.  Placing leaves of the ti ("Cordyline" sp.)  around one's home is said to keep away all evil spirits, and will cause the huaka'i pō to avoid the area.  Another thing is to always highly respect the night marchers which can result in great things.

Magical creatures in Harry Potter: Magical creatures are a colourful aspect of the fictional wizarding world contained in the "Harry Potter" series by J. K. Rowling.  Throughout the seven books of the series, Harry and his friends come across many of these creatures on their adventures, as well as in the Care of Magical Creatures class at Hogwarts.  Rowling has also written "Fantastic Beasts and Where to Find Them", a guide to the magical beasts found in the series.  Many of these are derived from folklore, primarily Greek mythology, but also British and Scandinavian folklore.  Many of the legends surrounding mythical creatures are also incorporated in the books.  "Children ... know that I didn't invent unicorns, but I've had to explain frequently that I didn't actually invent hippogriffs," Rowling told Stephen Fry in an interview for BBC Radio 4.  "When I do use a creature that I know is a mythological entity, I like to find out as much as I can about it.  I might not use it, but to make it as consistent as I feel is good for my plot."

Countess Dracula: Countess Dracula is a 1971 British horror film based on the legends surrounding the "Blood Countess" Elizabeth Báthory.  It is in many ways atypical of Hammer's canon, an attempt to diversify the studio's output from "Dracula" and "Frankenstein" sequels.

Cat sìth: The Cat Sìth (] ) or Cat Sidhe (] , Cat Sí in new orthography) is a fairy creature from Celtic mythology, said to resemble a large black cat with a white spot on its chest.  Legend has it that the spectral cat haunts the Scottish Highlands.  The legends surrounding this creature are more common in Scottish folklore, but a few occur in Irish.  Some common folklore suggested that the "Cat Sìth" was not a fairy, but a witch that could transform into a cat nine times.
