Let's make a simple solution: RealmDetails.php?ID=ABC where ABC=an integer from 0 to infinity (Theoretically)
Now type in the numbers 0, 1, 2, 3, 4. You will find that (rogue) doesn't count, and that only 3 and 4, being PeL and Madina, respectively, still exist. That's the end-all decider of who wins in survival of original realms (Neither, btw, since technically (rogue) will outlast everything.)
