The Valley of the Four Hills is a large, open valley with a rounded hill at each corner. Tall brush covers the ground, mingling with prickly weeds. A dark stand of trees looms at the far end of the valley between the largest hills. There is almost no undergrowth in the grove, just rank upon rank of gray pillars supporting its leafy canopy. Many areas of Fablehaven carry terrible curses and are protected by ghastly fiends. The grove in the Valley of the Four Hills is one of the most dreaded.
