Role Play terms are a very important part of RPing. They give you words to put in place of the simple words that are used in every day life. Ex. Instead of using tail, use tassel or banner. Something like that. Please use them.

The Hierarchy terms are rank terms. Learn these terms so you know your place in the pack as well as the other members place in the pack. It will be very helpful in the long term when joining, as well as RPing. 

The History of each Pack can be found here as well as the members who reside in the packs. Review the History's so you know which Pack is which and how they came to be.
