==Humans and the Cycle of Magic==
''Speech given by Keynote speaker, Ehran the Scribe“The Scribe” at the YET (Young Elven Technologists) fund-raising dinner.''
The Humans are confused.
This is their normal state of being. Their lives are so short, they never have time to think things through. I know this is a gross over-simplification, that there have been many brilliant Human scholars throughout the ages. Even the Leonardo da Vinci and the Einsteins, while brilliant enough to see a glimpse of the larger pattern, and imaginative enough to visualize a complex and interconnected world, still did not have the time to analyze their own thoughts. It takes years, sometimes hundreds of years, to get the correct perspective on ideas, even your own ideas. Humans just do not have the luxury of that time. They are also limited by their devout belief in not believing. Since the earliest recorded Human history, they have had stories of magic, great unexplained ancient civilizations, and other mysteries. The Humans chose not to believe these and thus, when the mother returned the magic to us, they became disoriented and confused, their normal state of being.
In all fairness, I must admit that most of humanity was not very advanced when the great mother took the magic away the last time, so it must be hard for them to deal with its return. What I am about to tell you must remain an Elven secret. I know that the Humans will eventually discover it, but it should be delayed as long as possible.
All things that the great mother gives us, she also takes away. Nature, as the Humans call it, moves in cycles the rising and setting of the sun, the seasons of the year, the flowing of the tide, it is always a cycle. Magic also runs in a cycle, it comes and goes from the Earth, as does the warmth of the summer sun. Its cycle is measured not in hours, as the sun’s is, but in thousands of years.
From a scientific viewpoint, magic, when charted, is a semi-regular wave form moving through the history of the earth. There are slight fluctuations throughout the wave, and the wave itself is not completely uniform.
The point in the cycle at which the world becomes magically alive or magic falls dormant is called the Threshold Level. Every magical race and, in some cases, each individual within a race, has its own specific magical trigger point for metamorphosis to occur, thus the transformation of the world takes place over a period of time. Traditionally, the Threshold Level has been set as the date of the Awakening of the first Great Dragon on the upswing, and the hibernation of the last Great Dragon on the downswing. The average time between Threshold Levels is approximately 5,200 years.
As the last age of magic came to a close, Atlantis was readying itself for disaster. The isle of Atlantis was protected from the forces of nature by the magic of its inhabitants, and thus it could not exist after the magic dropped below the Threshold Level. The Atlantean culture was a racial hybrid that had achieved both scientific and magical wonders, but in its later years, it turned against itself by fighting nature to maintain the island. As the end came near, a migration of technology and culture spread from the isle to the rest of the world. This is the reason mankind’s ancient calendars all start within 100 years of each other. The Hebrew, Egyptian, Chinese, and most importantly, Mayan calendars all show the direct influence of Atlantean culture.
The Mayan calendar is the most amazing, as it contains a complete description of the magic cycles, including this current crossing of the Threshold. The Mayan calendar was created in the year 3372 ʙᴄ (using the Christian calendar), just at the end of the last cycle. The Mayans described the cycles as “worlds,” and stated that only certain life forms made the transition from one world to the next. The calendar, written over 5,000 years ago, predicted the exact day the Threshold Level would be passed. If we Convert the Mayan dates to the current Christian calendar, it correctly states that the Threshold would be passed on December 24, 2011. On that day, the first Great Dragon was seen in Japan. The precision is amazing.
Atlantis sank on August 12, 3113 ʙᴄ, thus marking the end of the Fourth World and the beginning of the Fifth World. The Sixth Worldbegan on December 12, 2011 ᴀᴅ , and will end, according to the Mayan calendar, on April 4, 7137 ᴀᴅ.
We have the intervening time to enjoy what the Great Mother gives us and to use responsibly the double-edged sword of technology that our Human cousins have created. We must use both the energy of nature and the power of technology to try to fix the damage done by our short-lived relatives.
According to the detailed Wikipedia article on the ''WikipediaMesoamerican Long Count calendar'' a "World" lasts 1,872,000 days.
According to Ehran the Scribe's dates in the above speech, a high-mana World is 1,871,970 days, and a low-mana World is 1,871,270 days.
While the real life explanation for the discrepancy is likely that the game's creators had incomplete sources and/or made incorrect calculations based on the resources available in 1989, an in-universe explanation could be that Ehran's dates are correct, and the Wikipedia article's details are incorrect.
Based on the above numbers, one can calculate (see sources) the following start dates for each age
