Faries of Keltheria

Mentioned in a tale spoken by Omedion Kelsidion told by his father Lunaries Kelsidion.
" There once a city, the city of the elven empire, long ago it existed in the Emerald forest, perhaps you would not see the beauty behind the place known as the southern mainlands now but there was a time when it was the shineing jewel of the world.. it's forest was cared for by the people and creatures of the wilderness, the city that dwelled within it was named after the first daughter of the first emporor Nidiaria. But Nidaiaria was special you see it became a becon of hope to the creatures of Keltheria many mystical beings that crossed over through the divine tree, such as the fairies, the gryphon's, the woodfolk, and many others lived in harmony within the land itself. Though then there were no wars there were still threats to the forest that we and them had to deal with accordingly. My father told me a story once that there a young fairy princess, whom crossed over from a whole nother world, she and her people decided to live within Keltheria, and where my grove stands now used to stand the divine tree you see, so they bit a kingdom around this tree... the kingdom was hidden, and no normal elf or creature could find it, and for centuries they protected the tree and cared for the land, the princess and the fairies where a kind folk they would heal the wounds of beast that had been hurt or sick, they would grant their blessings on the elvish kin... they saw everyone as equal... but as time pasted and new threats arose, their beauty, their power, and their scource of immorality was desired, a few races in the rebellion heard stories from tortured elves of the divine tree, and though it is unclear what happened after Nidiaria's fall, the fairies, and the divine tree had been burnt down.. creatures that once crossed over, became stories, myths, and legends... I myself have trouble imagining it at times, but if you saw the things that I've seen belief, comes with ease..."
