Cyber-Island Chain
Also known as Cybernesia, the Cyber-Island Chain was putative location of micronations that shared some common history with the old Cyberia. These included U.P.E.C., Cyberland, Terra Novum, the United Imperium, Rocentia, Vivaldia and others.
The historic location of the archipeligo is in the Atlantic Ocean of contemporary Earth, running from southwest of Bermuda nearly to the Azores.
Currently, the Federal Republic of Cyberia and the Free Republic of Rocentia claim a presence thereabouts.
Geological Development
The following is from "The Developement of the Cyber Island Chain" by Admiral Kenneth K.Thacker
75-50 MILLION YEARS AGO: CONTINENTAL BREAKUP
Pressures begin to increase due to the super-continent Pangea’s continuing break up and a series of large faults begin to form splitting off a large chunk of the European continental plate and pulling it gradually in a southwesterly direction with the Atlantic Oceanic Plate. This area was rich in plant and animal life and many fossils from the Mesozoic era can be found today.
50-35 MILLION YEARS AGO: CYBER-ATLANTIC PLATE FORMS
As time passed the new Cyber-Atlantic sub-continental plate began to shift further southwest, away from the European continental plate. This was a period of great upheaval and large portions of the European land mass were torn away and many of which now exist as a chain of large islands extending for nearly 1000 miles. During this time, earthquakes and mass volcanism was the norm and in fact many of the smaller islands in the Cyber Island chain are a direct result of volcanic buildup.
35-10 MILLION YEARS AGO: CYBER ISLAND CHAIN DEVELOPS
As the Cyber-Atlantic sub-continental plate continued to move farther from the European continent, additional upheavals rocked the new islands of the Cyber Island Chain. The largest of these islands Cybsentia was torn into four smaller islands or island groups, Cyberia, Cyberland, Rocentia and the East Cyberian Archipelago. As time progressed these island groups have spread out further and further away from each other and each has taken on distinctly different geographic, geological and meteorological characteristics.
10 MILLION to 6,000 YEARS AGO: FINAL FORMATION
During this time period much of what can be seen in the modern day Cyber Island Chain began forming. During this time period the Cyber Atlantic sub-continental plate ceased it’s rapid southwestern drift as it began to meet increased pressure from the Atlantic Oceanic plate. It was during the first few million years of this time period that mountains ranges like the Aerie Spine mountains in Rocentia, the Wasulan Peaks in Cyberland and the Mattimean Range and Cyberia began to form. It was also during this time period that the northern most islands were buried under miles of glaciers that did not fully pull back until the end of the last Ice Age over ten thousand years ago. In the last 2 million years the Cyber Atlantic sub-continental plate has begun to slowly stabilize and the entire area is expected to eventually become more or less geologically stable. Due to continued plate tectonic activity however, the area is still considered one of the most geologically active in the world today. Also during this time period, much of the flora and fauna that can be currently seen today began to evolve.
