Writer's Block

First, I want to apologize for the over a month gap in my updates for "The Darkness Within." I had a bad case of writers block. And now, I've broken through, but the ideas come to me, aren't for "The Darkness Within," unfortunately. Fortunately, the ideas are for a fanfic, but I'm stuck for a title. So here's a rough idea of the basic plot;

A young earth pony lives in a subterranean community of all earth ponies. she breaks their biggest rule and is exiled, for life. She wanders around underground, fights a few monsters, gets captured and enslaved, fights monsters, gets rescued, grows up on the surface, makes friends, fights more monsters, gets in trouble, fights more monsters. It's a Terraria crossover. Oh, and it's set BEFORE the founding of Equestia.

Any ideas for a title?
