Cobble Cavern

In book 3 of Flin's Destiny and "The Earth Time Continuum," Raggleroot, an angry old man who has been imprisoned deep into the earth due to Flin's great grandfather, Hovgard, is determined to destroy the cathedral and all those in it with his deranged pits and seeds he has been engineering for decades. Meanwhile, Blade and his men have taken control of Clover Cavern, leaving the leprechauns to slowly lose their magical powers and at some point, they will surely die. But if you thought that was bad, the Earth Time Continuum which is the heart of mother earth, has been stolen and without it the earth, both down under and up top, will cease to exist. Is it destiny that this young man find and restore these lost treasures before it's too late, or will all come to an end?
