Eladrin and the Great Tree

The Great Tree grew and gave birth to the Four Seasons, the Eladrin. The Eladrin were thought to have originally been one being that cultivated the tree. Magic was born along with the tree, allowing the cultivator to divide themself into the four seasons: Spring, Summer, Autumn and Winter. Each of these seasons were thought to have inherited specific parts of the cultivator's personality. The tree's roots would span across the planes, connecting to and allowing them access to that same magic.
The Eladrin used the magic granted to them by the tree to protect it and keep the primordials at bay but were only capable of standing against them as a unified force. While they very rarely agreed on anything else, the four of them all agreed that the tree must be protected and stood together in the fight to preserve it.
The ever expanding roots of the tree would eventually touch gem stones deep beneath the earth, giving birth to gnomes that would work to purify the soil around it's roots. Other races would gather from around the world, seeking refuge under the light that was the Eladrin. Together they believed they were unstoppable, but their young minds would soon learn how naive they were. For when the Dawn came, the world knew to flee.

The Walking Dawn

Before the Great Clash, and before the Age of Darkness, Maegara, the Dawn Titan was the world's living sun. Between her slumber and her awakening, the world was in a constant state of death and rebirth. While Maegara was awake and mobile, the world itself would catch fire with very few living creatures able to seek refuge from this apocalyptic cycle. Even most of the primordials would flee to their respective planes. Maegara, being too powerful for even the collective might of the, still young, Eladrin had pushed them into a corner. To save the Great Tree, the Eladrin, made a united wish upon the tree, creating a new plane that existed parallel to the Material, taking the tree and it's other protectors with them. This would disrupt the flow of magic to all other planes, leaving them without until the roots of the tree had time to regrow and connect once again.

A New Home

Woodlands and other lush plants began to sprout and cover the new plane. The Eladrin, no longer in a constant state of war, were finally given time to relax and cultivate their new home. The young gods would nurture all manner of beasts and plants. They would bore many children who would later be called the Elves. With time, the Eladrin would immortalize certain animals as immortal spirits, each tasked with watching over a particular race.
After a time, with the lack of a sun, the woods began to wither. The darkness, called Shadow, that clouded the plane began to corrupt creature, water, plant and soil. Even the Great Tree itself seemed to cry out in pain. To save the tree and everything else that had yet to feel the corruption of Shadow's touch, the now much more experienced Eladrin, challenged the living sun once again and stole the life essence of the Dawn Titan. Using this essence, a lasting sun was creating for the Feywild. With the death of Maegara, the Eladrin had saved the creatures of the material plane by breaking the apocalyptic cycle. This, however, also began the Age of Darkness.
Weakened from both the battle with Maegara and the creation of the sun, Shadow took this desperate opportunity to corrupt Summer and many of his children securing it's hold on the plane. With all the Eladrin drastically weakened and the excess use of magic pushing the tree to it's limit, the conflict between the four of them split the tree and the plane in two, banishing all those corrupted to this new world. The Great Tree now simultaneously existed in both the Feywild and the new plane of darkness, the Shadowfell. The Shadow Tree's roots would also extend to the other planes, but instead served as roads that link the planes together which would later be called Shadow Roads.

A Family Torn Apart

Following the split of the plane, Winter would fall into a deep depression over exiling Summer to world corrupted by Shadow. Winter would dub herself unworthy of the paradise that was the Feywild and be unable to forgive herself or the others for not even trying to save Summer. Winter and her remaining children would leave, exiling themselves to the northern continent of the now dark material plane.
After several elven lifetimes in exile, Winter found herself still thinking of Summer but would never find the courage to try contacting him. Regardless of how long it had been, time would never ease her guilt. To escape her feelings, Winter would freeze her heart, locking away her emotions, resulting in the beginning of an eternal ice age on the continent her and her children chose to dwell on.
