That is a good suggestion, Kihyah. I've edited the rules now; only one claim per member, and after one month of inactivity your territory will be unclaimed again unless other pack members keep it active or you place a message of absence in the Away board. I'll start the actual unclaiming of territories in a couple of days.
Lanrox, the staff could do that, but really the idea of Wolf Life is for you to write your own story. You get to decide whether a hunter enters, or a dangerous lightning storm forms, or a drought hits and makes it difficult for your characters to survive. You have to make it interesting for yourself. For example, maybe while your wolves are out a bear enters the den and manages to take and kill one of the pups. It would be a tragedy, and you could work off of that for several posts. I am by no means saying you should or have to do this; it is just an example to go off of to make your role plays more interesting.
