The bogs where no men dwell have other, more vile and loathsome inhabitants - water and grave hags, foglets and will o' the wisps. For their staff of life they devour the worm meat of beasts, yet their true favored delicacy is human flesh.

Woe to any lone traveler led of the beaten path by a faint light in the distance! 'Tis not the glow of a pleasant fire in a cozy hut, but a lure used by foul swamp creatures to attract their prey. So gird your loins against the temptation of the supposed comforts awaiting you by a warm fire, and instead pray through the night to the merciful gods, for only they will let you tell the false from the true and only they can save you from evil in your hour of peril.
