Cataloging all the Grogs would require a tome the size of a medieval beastiary.

Their origin is in the DNA-shaping science of the Lifeweavers. They come in all shapes and sizes, from viciously cunning modified rats to multi-legged behemoths which could step over a bull elephant without raising a redwood-sized leg high at all.

Most people consider the Grogs just as bad as the Kurians, part of the same menace. While they were right during the days of the Overthrow, the Grogs have since been give areas of their own, perhaps as a reward for loyal service, and some groups of them act as free agents. None are particularly friendly to man, but alliances have in fact been formed under special circumstances. When the Paramount Kurian Lord known as the Lich King of Seattle's vassals started feeding on Grogs in the Pacific Northwest, some of them allied themselves with the Freehold Western Confederacy in opposition to the Kurians.

There are large, grey, slab-skinned Grogs which move like mountain gorillas and shoot like Olympic marksmen. There are moderately sized flying Grogs popularly known as gargoyles. Some stretches of ocean team with fish-frog creations, goggle-eyed and toothy. They attack anyone left vulnerable in the water, taking out a grapefruit sized chunk of flesh then waiting for the victim to bleed to death. There are long snakelike Grogs that look like an old tree trunk covered with debris until they bite you in half. Human DNA seemed to be a popular base with the Kurians, they have created Tiger-men, Ox-men, desert-stalking Lizard-men and ponderous Bear-Men. While none of these creations have been successful on their own in the wild, every now and then a Nomansland wanderer will come across and enclave of bizzarity living in a ruined town like a broken down freakshow.

Pity them or fear them, that is the question...
