From the back cover:
All around you lie the elemental forces ready to bend to your sorcerous skill: summon lightning from the sky, split the earth so it swallows up your foes, or spin them into the air with a typhoon. The spirits of the Air will serve you, the Earth gives up its dead to protect you, Water freezes at your touch, Fire-dwelling demons dart from your hands. You are an Elementalist with power over the Earth, the Air, Fire and Water. But you have not the power of Darkness that hold the world in thrall and which you quest to banish forever.
This fifth book in the Dragon Warriors series explains how you may become an Elementalist, drawing on the powers of nature. There are fifty new spells and a full-length epic adventure in search of the lost city of Fengil, Prince Of Darkness.
