You probably want to say "what was able to shake the whole library." Putting it in the present tense makes it a general question about what things, out of all the things in the universe, are capable of shaking the library. Among the answers to that question are earthquakes, ursa majors, and strong gravitational waves. But Twilight's certainly not expecting to find a gravitational wave in her front room. "What is able to shake the whole library like that" would at least make the question relevant, but that would still be a strangely detached way to think about something that is happening in your own home, since it's still fundamentally an abstract question about capabilities rather than a question about what just happened.



Also, like I said on Find Yourself , you shouldn't be putting "Hasbro" and "Lauren Faust" in quotes. The words do not own anything, because words do not have the right to own property, or for that matter any rights at all. Hasbro and Lauren Faust, the actual entities, are what you want to refer to.

For that matter, I don't specifically remember, but I assume I've told you before that "MLP:FiM" has a colon, not a semicolon. And now I'm telling you again.



Your imagination's pretty shaky, Twi. Maybe you should get that looked at.
