Pa Ri Tor has existed for about 6 years, through some serious drama. It has survived the typical SL slow times that happen around the holidays. It is very likely to continue to exist as long as Panther Ridge exists, since the two are effectively one. As this blog's main page says, we have Dutch and Phee to thank for keeping the sim going, so the tribe has a strong footing to also keep going.
Pa Ri Tor is alive and well, and we're still strong roleplayers who follow the books as much as possible. In the end, that's all that matters.
