Shapeshifters

Shapeshifters are found among all the sentient races, with the exception of the fae.

Origins
The Plague

Shifting
Shifters take on the animal form of the native fauna around them, and their shift shows their ranking within their pack. A pack leader will be an apex predator, and the weakest member of the pack prey animals.

Packs
Based on geographical area. A pack will be no smaller than five shifters, and no larger than thirty. Their territory will be whatever size needed to encompass the members. A pack within a crowded city may have a territory of no more than a block, while a country pack of the same size may claim several miles.

Freshwater
All freshwater Merpeople are shifters, due to the origins of their sub-group.
