First "Regulars" climbed with Zahard himself, and these joined Zahard on the Floor whence they originated. For instance, we know that Grace Mirchea Luslec joined on 80F, and that Zahard created some Princesses during their climb whom were "Regulars" as well.

As for the first "modern" version of Regulars, I can think of two alternatives from the top of my head:  I imagine there were lots of Zahard and the 10GW followers by the time Zahard ultimately created the system where the Tower can be selected to climb. Therefore, some of those who reached the top with them could have been disseminated across the Floors to conduct the tests. Another possibility is that Zahard Administration simply hired locals to administer the tests. This would explain the Shinsoo ability boost received by the test administrator that always seemed somewhat superfluous in the current setup (i.e., Rankers can overwhelm Regulars without this boost), but that would make sense if the test administrators in the past may have been considerably closer in power to those whom they were testing.
