Gitrog monster

The Gitrog monster is an enormous frog that lives in the depths of Lake Zhava, which is located in the highlands of Nephalia on Innistrad, near the border with Gavony.

As the madness in Innistrad grew, the villagers of a small village near the lake started to fear the monster which they knew from stories. They began to sacrifice sheep the Gitrog, and later humans. In the end, most of the village was without occupants.
