We know absoultely nothing about the history of the Tower, before Zahard entered. The whole history as the people of the Tower perceive it pretty much started with Zahard, maybe some ancient legends before that. The main point here is that people wouldn't know what an Irregular is even if they saw/met him. They couldn't communicate since there were no pockets and I highly doubt they have the patience to learn a new language, especially if you consider that they are like actual gods to normal Tower inhabitants(people couldn't use Shinsoo back then).

There are legends in the Tower of Demons who fought against God, or something like that. It very well might be that early Irregulars were perceived as Demons, or turned into such after certain events. I don't think that any of these early Irregulars are still alive, but I really think that it didn't all start with Zahard. I actually think that the Tower has probably changed a lot throughout the years. One of the biggests indicators for me is Revolution. I think that it was a progress, which Irregulars were meant to go through naturally while climbing the Tower. The GoG said to Baam that he should learn what it means to be truly alone for example.(I'm aware that the GoG also has limited knowledge, because he was made by the workshop, but the idea of Revolution must have come from somewhere I guess,)

Maybe in the early versions of the Tower there were no people inside. Maybe the Irregulars went crazy because there was absolutely no one inside to be found for hundreds or thousands of years and they went crazy and were unable to go up further.

Then people were put inside and Zahard and the 10 for example had to find a new way to go through Revolution.

The biggest indication for me is though that Headon made a deal with Zahard immediately after he/they entered the Tower.
