Shadow of the Elves.

Almost microscopic in size, there exists a world hidden within our own; the Meadowlands is a delicate world of flowers as large as redwoods, and insects the size of dragons, where peaceful fairies take wing and comical trolls haunt the lowland swamps and inhabit dark, hidden caves. Without warning, a shroud of evil is creeping across the land... deep in the Dark Wood at the edge of the Meadowlands, the Elves have built their citadel in a gnarled ancient tree. Their malevolent leader, Lord Kann, lusts after control of the entire fairy empire and has vowed to conquer every corner of this magical realm.
