Sorien? That's a really old name, and I mean older than the very first private server!
I think you've become misunderstood somewhere because "Sorien" was only associated with a hack. If you're referring to a server where you can use his hacks then I think you're so out of date you should be wearing a Roman robe and shouting veni vidi vici at everyone around you.
If you are just looking for a server which you can use Sorien hacks on then I would advise you not to ask.
That is about as polite as I can say to anyone looking for a pserver that you can use Sorien hacks on. Fortunately even the lowest of the low pserver devs don't use Sorien compatible clients
