Phoebic Ages

As with all historical events of the cyclops-mountain giant hilltribes, the exact dates of their migration from Arokha to Eren are vague. Historians and archaeologists estimate that these groups first began to cross the land bridge between the two continents around eight thousand years before Year Zero. However, the bridge was already succumbing to rising sea levels with the decline of the second ice age, giving the ancestors of the hilltribes a short few centuries to emigrate before the isthmus was swallowed up by what is now the Niloghe Sea.

In the warm shallows off the coast of Sikano, the sirenian Umibōzu began to form recognizable culture around seventeen thousand years prior to the start of the Second Rise. During this period, they constructed the cairnroads across the seabed that would come to be essential navigational guides for other species.

Centaur civilization is estimated to have formed around one thousand years before the Third Moon, in north-central Arokha. Though mostly nomadic and not especially advanced in technology, some centaur herds discovered the principles of agriculture and adopted a more sedentary lifestyle.

Sphaeran global recorded history is typically represented in years referencing the second appearance of post-Venusian civilization in the region around the Pillar of Heaven's remains. However, the rise of a culture to technological civilization is a gradual process, and thus Year Zero is agreed to be the year when the Third Moon graced Sphaera's night skies. Concurrently, the harpies and karura at Pillarfell began to rediscover the lost secrets of metallurgy and advance to a new Bronze Age.

Several hundred years after the start of the Second Rise, the tengu of eastern Sikano formed a cohesive, technologically-capable society that ruled the canopies of the Serpent's Coil range, spreading to the central woodlands of the continent over the coming centuries.

In the mid-20th century SR, a new player arrived on the Sikanese cultural stage. The gorgons, venomous lizardfolk from the eastern scrublands, picked up tool use rapidly from the tengu and treants with whom they shared geographic space. They began to organize, mastered agriculture, and soon were experimenting with metallurgy. In time, their future civilization would become a global political power.

In Sikanese Autumn of 2155 SR, the three gorgon tribes of eastern Sikano solidified their alliance by forming the Gorgonic Tribunal. The Sthenic Tribe of the badlands, the Euryalic Tribe of the woodlands, and the Medusic Tribe of the islands sent their chieftains to meet in the coastal city of Karshaan and, after a long session of negotiation, peace was established among the tribes.
