“…so Arcturus attempted to set a magical waypoint to the desired destination, so that the need for rough guesstimates about relative changes in geography would be much easier to factor.”  Twilight had to stop and take in another deep breath before continuing.  “While he was unable to make his magical map, he discovered something else entirely.  His spell revealed what he described as ‘the golden threads of the world.'  Apparently he had inadvertently revealed the lines of the universe, the very foundation of the cosmos.  He called these lines, ‘lifestreams.'  These lines all combine to form what was to come to known as the ‘Empyrean Web,'  or the lines of the universe.” Twilight's tone became more excited.  “I have only ever seen them once, myself.  So it’s rather difficult to describe, but imagine golden lines everywhere.  They are completely invisible and intangible, normally.  They can only be seen using the same spell he created thousands of years ago.  They pass through solid objects unfazed, like a beam of light would pass through glass.”  Twilight began to demonstrate by pointing all over the room with her hooves and connecting invisible threads to opposite sides of the lounge, looking about as if she could see them all before her.  “But that wasn’t the only thing he discovered.”
