Frogs

The plague of frogs that has afflicted the area is the doing of Wandamorel Moonshadow. The frogs are her psychically controlled minions.

She gained this power, among others, after pledging her soul to the elder god Yog-Froggoth after she dies.

Can be encountered randomly about town as individual frogs, swarm of frogs, or giant frog.

After Wandamorel is slain, the frogs go back about their business.

''The elder frog, the fiend of the underpond, the ancient green terror spawned from the depths of hell itself, mauler of psyches and flayer of flies... you have dared to summon... YOG FROGGOTH.''

The fearsome Elder-Frog Deity, YOG-FROGGOTH. He appears only rarely in corporeal form, residing normally in his own plane of existence, which is filled with frogs. The very sight of him inspires both horror and loathing, his very form seems to write beneath the eye of the unwilling spectator, unable to look awak. His deep red eyes gaze into your very soul, and hunger for your sanity. To know YOG-FROGGOTH is to lose your sanity - we are all as flies beneath his giant lily pad of the stars.

The few who have bound their lives in service to the Elder Frog know power beyond reckoning, meted out from his galactic essence to the minds of only his most oyal advocates. But to attain such forbidden knowlege is to forfeit your soul. After death, the faithful of YOG FROGGOTH go not back into the boundless deep whence the souls of man are drawn out at birth, but enter the plane of the frog god, and experience non corporeal horror impossible to dream of in this world...
