Assemble the Heights

I stack the bricks, it's like I'm climbing higher (I'm buildin' up, I'm buildin' up I'm buildin' up, I'm buildin' up) All 'cross the scenes, all through the saga's fire My grip's intense, but I won't tire (I'm buildin' up, I'm buildin' up My fingertips, they're moving with desire Each piece I place, we're scaling spire by spire (I'm buildin' up, I'm buildin' up) Through shaky hands, I feel the heroes' power Can't quit now, I count the hours (I'm buildin' up, I'm buildin' up)
