I see you've found this- awesome! I hope this will answer your questions, if not, comment below!
Step 1: Choosing a name.
Believe me, this one is a toughie. Sometimes this is the hardest part! But don't fret, I can help with that!. To start- think, do you want the name to be named after the pack or something else? I usually name mine on a occasion or theme of the RP. Let me think of a example.. Aha! Let's say my role-play was about a tornado that wrecked the prey population, I could call it 'Famine' or if a pack wrecked the population, try 'Tornados' or 'Tornado Pack'
Step 2: Information
Be sure to describe the pack and the earth/nature around it! Lets say the pack gives off a lively vibe, and it is currently Winter, with prey being scarce. Just come up with something like that!
Step 3: Pack Rankings
This can be annoying, trying to remember the ranks. Well, if you can't remember them, make up some ranks! Or look at my main account's [Rosedogs5] << Disasters >> Role-play! It has a whole list of rankings!
Step 4: Pack rituals/events
Each pack is unique, each has it's own rituals and/or events. Try making them up, be creative!
Step 5: Pack laws
Each pack has it's own laws to abide by, and if broken comes a punishment!...
