I don't know if this is real or not i found this in a book.

In the 12th century,a letter adressed to the byzantine emperor manuel began to circulate around europe. The letter clamied to be written by a mysterious preist king called prester john,who ruled a huge christian kingdom in east. His kingdom was a fabulous land,brimiming with riches and untold wealth. Unicorns and dragons roamed the beautiful land,while a fountain of youth kept all it's citzens forever young. It had many strange and wondrous beasts, including salamanders that spun fireproof silk!
These letters naturally fired the imagination of all those who heard of prestor john's kingdom. The only problem was that no one knew where it was. Many went in search of it, but no one ever succeeded in discovering this mysterious kingdom. Eventually, people decided that the letters were hoax and such prester john's land as such never existed.
So is this true or hoax.
