Nah, none taken! I saw a similar comment on another thread and I've been sorta nervous sweating since.
Funny thing is, I actually considered "Blank City" at one point too ages ago, but I actually chose otherwise because at the time I knew of tons of other things called names like "Nightmare City" or "Angel City" so I was actually avoiding that trope that was pretty popular at the time.
And I guess to actually contribute to this topic, and I fully admit I might be biased, but I think most title lines are okay as long as you're avoiding the...classic fantasy cliche words (darkness, light, destiny, chosen, angel/demons to an extent).
It's already been said, but please avoid impossible to pronounce names. Like man, I love Disgaea, but I still don't fully know 100% to this day how to pronounce it and had to double check the spelling just to make this post.
Also, alliteration is always appealing in titles. Not at all necessary, but it always makes for something that rolls off the tongue nicely.
