The Falanholme Chronicle.

A Bright, and Shining Land. Book 3.

Falanholme now stands alone. All her neighbouring Realms have been overrun and subjugated by the Forces of The Darkness. The time has come for the Guardians of The Light to gather such allies as are left. To the north lies the Dragon Eyrie of Storien-Rhudd. These Dragons, it is whispered, are the victims of a terrible "Dread Imposition" laid upon them by the Lord of the Underdark, who had transformed them into Dragons; fully shunned, with no hope to ever redeem their Grace in reprisal for their defiance of his objective to turn all back to Chaos, as it had been in the Beginning of Days.
In the Eyrie, there is an ancient stone tablet upon which is carved a riddle which, if solved, will return the Dragons to their true form. The key to this riddle lies many leagues distant in the east... where the Forces of the Darkness are marauding. if a covenant is made, and the Dragons agree to assist the Forces of Falanholme in the destruction of the Forces of the Darkness; then with the way open to the east,  the key to the riddle can be recovered and used to return them to their rightful form.
