Atakus' BIONICLE.com quote is: "No one rides into Roxtus without getting past me. And those that do, heh, never leave." It sounds intimidating at first, until you realize Atakus is admitting he's bad at his job.

I thought more about the quote, too, and realized there's quite a bit more going on here than at the surface. When Atakus says "getting past" does he mean "sneaking past" or passing him at all? Are there certain people he is supposed to let in, or is he supposed to turn away everyone? I detect no fewer than three possibilities:

1) Atakus' job is to prevent anyone from entering Roxtus, and those who do enter Roxtus without him knowing are caught and killed. (This interpretation doesn't work for character reasons. It makes Atakus sound incompetent for sometimes failing to keep people out. Sure, it makes me not want to try going to Roxtus, but because of whoever kills me once I get inside, not him specifically. The "heh" makes it sound like Atakus is trying to talk himself up.)

2) Atakus' job is only to prevent some people from entering Roxtus, but some others are allowed in. (This interpretation fails because it indicates that even those who are allowed to visit end up getting killed.)

3) Roxtus is such pleasant and welcoming place to live that everyone who visits inevitably chooses to stay there of their own accord. Atakus' job is to make Roxtus sound scary to stop everyone from trying to live there. (This is the least likely of the three possibilities, but as stated, Atakus' words do leave this a distinct possibility.)
