I like option number 2. It fits well with the definition of an Exis.

I also like the idea that Phantominium's powers don't work on the Zahards because Zahard himself is an outsider, and Phantominiums Exis domain of influence is the Tower itself. That way he could "collapse the whole tower if he wanted to" like SIU stated. It would also make sense why he didn't (couldn't?) harm the Zahards. This theory is only viable if there is a difference in the way that "blood" is passed on in the Tower. Although the Family Heads themselves are "Outsiders" and would not be subject to Phantominium's influence, their children (high rankers) carry their physical blood in some way. Yuri Zahard (and the princesses) carry the "blood of Zahard" but it is clearly not his physical blood. The blood of Zahard is literally a part of Zahards power...possibly making them an entity like Zahard who cannot be harmed by Phantominium.

One thing about this theory is that it explains why Phantominium broke into the Palace in the first place. Zahard had been calling himself the "King," a title that appears to reserved for Exes. If Phantominium had domain over the Tower, then he would be called the Tower King or King of the Tower. So Phantominium was pissed at Zahard for claiming authority that was not his.

Of course, other than the flaw that I outlined above, the other major flaw here is that Phantominium is one of the top five Exes, and the power of an Exes depends a lot on his/her domain. And the Tower seems like a pretty weak domain for a top five Exis.
