All that is possible. Plus, too many assumptions about the Irregular testing system so I edited the tests page to reflect it. Nobody even knows for now, how they were originally conducted.

Oh and apparently, the first battles in the Tower were fought against Shinhueh. Of course, depends on what kind of shinheuh they fight against. If it's that cute Net Dolphin, not much of a challenge.

Then again, maybe the tests started off easy and then, got a lot more difficult, after some time.

one more thing: some of the Floors were conquered by Zahard's daughters. If that is really true, it means Irregulars can get to skip a Guardian's test. Of course, as long as they don't skip the other tests(Guardian's test) And if it's in modern times, then it means no skipping the Regular testing system.

About Urek, he climbed through the normal way, right? I wonder what that even means.
